  1. Weather Chat Megathread

    I can easily sum up those three paragraphs in two words: Hurricane Nadine. (Seriously, that one must've given every meteorologist on the planet a migraine)
  2. Weather Chat Megathread

    Yes, but it doesn't make sense how Maria's wind is not increasing. A decrease in pressure ALWAYS means an increase in sustained wind speed. Also, Lee is showing all the signs of a rapidly intensifying storm nearing major hurricane status. It really doesn't make sense at all.
  3. Weather Chat Megathread

    Okay, there is no way Lee isn't a Category 2 or 3 by now. Despite its incredible organization and pinhole eye, the NHC still says Lee is just a Category 1. Meanwhile, Hurricane Maria's pressure continues to drop, which indicates that its wind speeds should be increasing...but they're not. What the hell is going on with these storms?
  4. Weather Chat Megathread

    It reminds me of Hurricane Igor at peak intensity - except like 20 times smaller. Lee's wind field is still only around 45 miles, while Igor managed to get to about 950 miles.
  5. Intergalactic Development Thread

    No...because there's not much TO use as a base system . Seriously, it was just the two stars and one planet. That's it. You can use my artistic rendition of the system on the Whole Solar System thread for inspiration, however. It contains all the five planets and is a lot better than what I was originally going for with planet designs for IA-Revived.

    Lee has now become a hurricane - a very tiny one at that. Hurricane force winds only extend out to 10 miles! What a midget! The NHC forecast cone predicts Lee to get very close to Category 3 status, but considering how well organized it is, it seems likely to reach major hurricane status within the next day or two. This is the first time in over a CENTURY that eight hurricanes have formed in a row.

    @SaturnianBlue Something interesting has been going on with Hurricane Maria today. Over the last 24 hours, its central pressure has dropped from 960 to 946 mbar, yet its winds have decreased to 115 mph. However, the drop in pressure, signs of an EWRC, and the increased organization shown by the development of annular convection leads me to believe one final episode of rapid intensification is about to begin. This is, actually, right on schedule for the GFS models.
  8. There are no telescopes. All our discoveries are done by going through and/or analyzing Kepler and K2 data.
  9. Weather Chat Megathread

    Um....this isn't normal. Maria plz stahp @SaturnianBlue
  10. Weather Chat Megathread

    Over the last day, Hurricane Maria's eye has collapsed and its structure has remained somewhat "blobby" and disorganized. It even appeared to have TWO eyes, as there were two dips in pressure at the center of the storm this morning. However, while the center is not perfectly organized, the eye is now back. I'm assuming Maria underwent an EWRC, which may cause it to strengthen into a Category 4 again. The GFS, HMON, CMS, and other models are all expecting a rather significant increase in intensity by late Sunday and early Monday, possibly close to Category 5 intensity.
  11. THE DAILY ROUNDUP These past two weeks have seen some major development in the knowledge of several exoplanet systems, as well as the discoveries of many more interesting worlds. EPIC 210693462: I've been teasing a HUGE reveal about this system for a while now. Originally, it was a red dwarf less than a third the size of our Sun with a likely rocky planet nicknamed Natalie orbiting within the habitable zone every 31 days. After the initial discovery, Ian Crossfield said that the Exoplanet Explorers team would use the Keck Telescopes to take a closer look at the system in late summer to figure out how large the host is. This would, as a result, enable us to determine how large Natalie is and whether it is promising or not for life. On September 10th, 2017, the data and images gathered were uploaded to ExoFOP by David Ciardi. This is the image of EPIC 210693462: Whoops, I forgot to say "stars", plural. It turns out that EPIC 210693462 is something none of us on Exoplanet Explorers ever expected: a binary system. Libmar96 was the first to stumble across the results, and he was initially quite pessimistic about the results. The problem with transiting planets in binary systems is that the planets are ALWAYS somewhat larger than initially expected, as the planet would need to block more light from the single star to produce the dip seen in the light curve. Libmar suggested that Natalie would not be a rocky planet, but instead a gas dwarf. However, that does not appear to be the case. The EPIC 210693462 binary is nearly equal in size, which would mean that any planet orbiting the primary would be 30-50% larger than initially determined with single-star data. This means that, taking into account the original radius value of 1.278 RE, Natalie would be between 1.66 and 1.92 RE if it orbits the primary star, a size range most probable if the planet has a significant amount of water in its composition. Instead of being a terrestrial Earth-like world or a hostile Mini-Neptune, Natalie could instead be like the Star Wars planet Mon Calamari - a life-friendly ocean planet with twin suns. But what if the stars aren't red dwarfs? That actually seems unlikely. Look at the scale in arcseconds. Both stars are incredibly tiny, and they're only separated by 0.84 arsec. This, along with the spectroscopic data gathered by multiple observations, suggests that the two stars are most likely M-dwarfs. They may even be much smaller than the original 0.312 RSun size estimate given by Huber et al. KEPLER-90: I also teased new findings about this system over the last week or two. If you're not familiar, Kepler-90 is the first (and only) 7-planet system found by the Kepler mission. It is like a more compact version of our Solar System - inner rocky planets, mid-range Mini Neptunes, outer Gas Giants - orbiting a star around 20% larger in radius and mass than our Sun. Using a new beta version of LcViewer and an improved BLS Search, shutcheon did an analysis on the system...and found THREE likely new inner planets! These new worlds are 0.80, 1.24, and 1.20 times the size of Earth and orbit every 3.0351, 14.4481, and 18.7855 days. All of them are perfectly in resonance with each other and the other two inner planets, Kepler-90b and Kepler-90c. Things eventually got even MORE complicated, as I managed to find TEN MORE SIGNALS within the group of inner worlds. Most of them are either randomly aligned stellar noise or artifacts from the other planets. However, a few signals hold promise. The most likely of the bunch are, as of now, designated KOI-351.13 and KOI-351.14. Candidate 13 is around 0.77 RE and takes 6.760 days to orbit Kepler-90. The other potential planet, Candidate 14, is around the same size at 0.79 RE but takes 8.454 days to orbit the central star. If real, this would mean that Kepler-90 has a total of TWELVE planets, even higher than our Solar System and the HD 10180 system! Because all 5 of the new candidates are so small, it's probably going to take a while before any of them get confirmed. It's also possible that some of these are false positives, while some of the other possibilities I've found are real planets. Very confusing. KEPLER-20: Another confirmed Kepler system joins today's Daily Roundup. It has 6 confirmed planets, 5 transiting and one that is not. Two of the planets were the first Earth-sized planets found by Kepler, while 20b is one of the very few "Mega-Earths". Shutcheon managed to find a potential seventh planet, this time a tiny 0.26 RE object orbiting every 0.403727 days, Think of it as The Moon from Hell. However, closer analysis revealed that this object may have a longer orbital period of about 1.232102 days, putting it in a 3:1 resonance with Kepler-20b. EPIC 210897587: A new find by Vidar87. Using newly processed K2 Campaign 13 data and an upgraded BLS Search, he found THREE likely rocky Super-Earths orbiting a small red dwarf star. The third one is potentially habitable! C02: 1.03 RE, 6.343 days, 0.049493 AU, 473oK, 34.7 sigma. C01: 1.44 RE, 13.855 days, 0.08332 AU, 365oK, 39.7 sigma. C03: 1.16 RE, 40.661 days, 0.17079 AU, 255oK, 28.4 sigma. This system is absolutely amazing. All of the three planets are most likely real, and would've been confirmed by now if scientists had access to this data earlier. Plus, that final planet is one of the best candidates for potential habitability ever found by Exoplanet Explorers users. Its longer orbital period puts it smack within the habitable zone, giving it just about the same amount of stellar flux Earth receives. It is only a tad larger than Earth, and may be freely rotating if its orbit is eccentric enough. Based on its radius and estimated stellar flux of ~1.00, EPIC 210897587.03 has an Earth Similarity Index value of 0.95!!! EPIC 210736056: Another multi-planet system found by Vidar87 with a potentially habitable candidate world. The host star is significantly smaller than the previous star at about a quarter the radius and mass of the Sun. There are only two planets in this system, but both are quite unique. The first, EPIC 210736056.02, is the smallest at just 0.88 RE, not that much smaller than Venus. It is also likely similar to Venus, as its orbit of 9.944 days places it at 0.057162 AU, within the "Venus Zone" of the system. The equilibrium temperature of 333oK suggests a stellar flux around twice that of Earth, which would evaporate any water and lead to a terrible runaway greenhouse effect. The second planet, EPIC 210736056.01, is significantly more promising. At 1.32 RE, it's exactly 50% larger than C02, and orbits significantly further out at 0.11675 AU with a year of 29.024 days. This puts C01 within the outer part of the habitable zone and give it an equilibrium temperature of 233oK. This is just about the same as Proxima b and TRAPPIST-1e, indicating a stellar flux 2/3rds that of Earth. The calculated ESI value for this planet is 0.83 - not as good as EPIC 210897587.03, but still VERY good and indicates a potentially life-friendly planet. That's all the significant findings for this week. Vidar87 found some other candidate planets, which you can see HERE. While all interesting, they're quite terrible to live on, so I decided not to cover them. Expect some more potential new candidates from known Kepler systems in the next Daily Roundup.

    It seems like Hurricane Maria is back to Category 4 status. The latest aircraft recon pass through the storm's eye showed a significantly lower pressure of 954 mbar (down from 960 mbar a few hours ago) with winds of 120 knots (about 140 mph).
  13. Two things:

    1.) I'm working on Interstellar Adventure Revived again! Currently rearranging the orbits of Sancho's moons before making some big changes. 

    2.) It's been a month since the eclipse. *upset Wookiee noises*

      Meanwhile, the eye of Hurricane Maria has rebuilt itself and the storm's overall organization has significantly improved. This means one thing: it's going to intensify again. 

  14. Weather Chat Megathread

    Hurricane Maria's eye has fully regenerated. It's looking a lot more organized and powerful than your regular Category 2/3, but as of now it's still holding that intensity. If it does resume strengthening it won't be until it has moved a significant distance away from Puerto Rico and the Dominican Republic.
  15. Intergalactic Development Thread

    @EricL I think Kepler-296 would be a cool choice. It's a five-planet system around one member of a pair of binary red dwarfs, two in the habitable zone. Plus, I once used this system for IA-Revived, so it would be cool for it to once again be used in a Kopernicus planet pack. Other multi-planet systems you may want to use are HIP 41378, Kepler-55, Kepler-62, HD 133131, and/or Gliese 3138.
