TEMS (Transiting Exoplanet Moon Search) One of the main goals of the IRVEES program is to not just find exoplanets, but also exomoons. The hunt for moons of exoplanets has not gone very well. There's a group called HEK (Hunt for Exomoons with Kepler) that tries to find Transit Timing Variations (TTVs) caused by an orbiting exomoon. So far, they haven't found any. But that doesn't mean this method isn't successful; it's just the target's sizes and differences. Most of HEK's targets are either hundreds of light years away, or have dim host stars, or are rather small exoplanets. I plan to take on that challenge. With TEMS (Transiting Exoplanet Moon Search), not just any planets are selected. They first have to pass at least 2 of these three Checkpoints that will determine if they may have a moon and if it can be detected: Is it close enough to Earth? Can it easily be detected by the transit method? Is its host star brighter than magnitude 15.5? Distance from the planet system to Earth is the most flexible of the Checkpoints because of how the other two affect it. If the system's star is over 1,000 light-years away but the star is brighter than magnitude 15.5 and the planet can easily be spotted, then the distance can be up to 3,000 light-years. However, to make TEMS results as clear as possible, systems within 1,000 light-years should be considered. A good system is 55 Cancri A (Copernicus). Next is how well the planet can be detected. A small planet orbiting a large star can slip through the imaging software on some telescopes, making TTVs impossible to find. But a planet that can be detected with a minimum scope of 10-15" is a good choice for TEMS. Finally is the star's brightness. A dim star doesn't have a huge effect on TEMS, but a target system that can't be seen is a huge issue. Now that those Checkpoints are out of the way, there is one other thing that needs to be considered: whether or not a target planet can even have a moon. To find out if a moon can be stable around the planet for at least 0.6 billion years, I would have to use Universe Sandbox 2. If the moon is destroyed or ejected withing 0.6-1 billion years, then the target planet will no longer be a target. Target Exoplanets: Ourania (Kepler-11g) Kepler-443b Aristaios (Kepler-452b) Hubal (WASP-14 Ab) HAT-P-2b Potential Targets: Kepler-18d Kepler-32d Kepler-37d Kepler-89e Kepler-14b In order for a moon to be confirmed, the TTVs must be very small and happen "randomly." Since the planet's year and the moon's orbital period won't be the same, the TTVs would seem to be random. However, I will probably update this with a better confirmation method. Candidate Exomoons: None ATM Confirmed Exomoons: None ATM People can help participate in TEMS if they want to. All they would need to do is review the timing of each transit, if there is a huge amount of data to work with. Several people may need to go over 1 data set if multiple planetary transits were observed.

Also, I may try to look for moons of my own planets. Schedule: June 14th: Observations of HAT-P-22b starting at 22:37 UST; Getting used to equipment and collecting first data set to find a possible moon to this planet. *Note: Kepler-32d's host star is magnitude 15.1. That may be too low to be a target system of TEMS.
