Here is my Kepler-47 analogue for the "Lonesome Stars" contest. I also wish for this to be a published system.

Name: Hydrox

Age: 5.5 Billion years

Mass: 1.1 Solar masses

Diameter: 853378 km

Density: 840 kg/m³

Surface Temp.: 5517^o Celcius

Semi-Major Axis: 0.0993 AU (From the barycenter. The barycenter's SMa is 12816 Light Years.)

Description: Hydrox and Kerleen originated from the center of the galaxy, until they got too close to the central black hole. Luckily, Kerleen was not snatched from Hydrox, but all their planets were, and then the two shot off into the distance as hypervelocity stars. They are currently the fastest hypervelocity stars we know of, shooting off at 0.8891435724252677373674743385847889043% the speed of light.

The System has been accepted for both the project and the contest. You may check it in the accepted systems tab. If you don`t like any changes that have been put onto the final draft. Be sure to PM me. (PS i have wifi now :D)

@Galacticvoyager, can you pubish the Mena system from earlier, too?

And another one. (Wait I just realized that I'm the only one making solar systems at this point. )

Name: Mena A

Age: 3.74 Billion years

Mass: 1.8 Solar masses

Diameter: 12.2 km

Density: 4.75E+14 g/cm³

Surface Temp.: 272385^o Celcius

Semi-Major Axis: 100 AU (From the barycenter. The barycenter's SMa is 34000 Light Years.)

Eccentricity of orbit: 0.2

Parent Body: Mena Barycenter (Barycenter's Parent Body is Nee'Kra)

Inclination: 67^o

Type: Pulsar

Rotation Period: 0.0058 seconds

Description: The Mena system used to be a trinary system, with Mena A being separated into Mena Aa, which would become the pulsar we know today, and it's yellow dwarf companion, Mena Ab. One day, Mena Aa blew up in a gargantuan supernova, which pulverized the forming planets around captured star Mena B and reverted the star back to the beginning of accretion. Eventually, Mena Ab began to die, and become a red giant. Mena Aa, being a pulsar, started stealing the star's material, and it began to spin faster and faster, until it stopped getting faster because the companion had reverted to a planetary state. This newfound "planet" is now known as "Auneme". And to this day, Mena Aa (Now Mena A) continues to spin very fast.

 

Name: Auneme

Age: 3.41 Billion years

Mass: 0.684 Earth masses

Diameter: 5589 km

Density: 5.59 g/cm³

Surface Temp.: 104^o Celcius

Semi-Major Axis: 0.4 AU

Eccentricity of orbit: 0.2

Parent Body: Mena A

Inclination: 67^o

Type: Rocky Sub-terran

Rotation Period: 68.6 days

Orbital Period: 68.6 days

Description: If you've read the description for Mena A, you'll know that this planet used to be a star. Now THAT'S cool!

 

 

Name: Mena B

Age: 1.87 Billion years

Mass: 0.725 Sun masses

Diameter: 460599 km

Density: 3.52 g/cm³

Surface Temp.: 4596^o Celcius

Semi-Major Axis: 100 AU

Eccentricity of orbit: 0.2

Parent Body: Mena Barycenter

Inclination: 67^o

Type: K5V

Rotation Period: 16.4 days

Description: The reason why Mena B is so much younger than Mena A is because this star was captured by Mena A's gravity, which was increased because Mena A was bigger and had a binary companion which eventually became Auneme.

 

 

Name: Laavae

Age: 1 Billion years

Mass: 1.48 Earth masses

Diameter: 6770 km

Density: 6.78 g/cm³

Eccentricity of orbit: 0.43

Parent Body: Mena B

Inclination: 88.8^o

Type: Irony Super-terran

Rotation Period: 3.08 days

Orbital Period: 3.08 days

Description: The first planet in the Mena B system, Laavae is named after it's extreme summer, when it's completely covered in lava. Laavae would have much cooler summers if it didn't have a thick atmosphere similar to Venus.

 

 

Name: Vernust

Age: 1.01 Billion years

Eccentricity of orbit: 0.0

Parent Body: Mena B

Inclination: 67^o

Type: Rocky Super-terran

Rotation Period: 1.99 days

Orbital Period: 152 days

Description: Vernust is a planet inhabited by sum really bad aliens. Like, so bad that they kidnapped most of the population of their neighboring planet Manno and de-terraforming it so the inhabitants, the Mofeku, couldn't have a home. What a bunch of jerks!

Eccentricity of orbit: 0.52

Parent Body: Vernust

Inclination: 85.8^o

Type: Irony Moon

Rotation Period: 3.93 days

Type: Rocky Super-Terran

Rotation Period: 3.43 days

That is, until their neighbors at Vernust basically kidnapped most of the Mofeku and then de-terraformed the planet so the remaining couldn't live there anymore. Moral of the story is: Have defenses against aliens until they prove they are friendly.

Upon reviewing of the system, I am happy to inform that it is accepted. You may check it in the accepted systems tab on page 1.

The Moon that is in red means it is too unstable for the finishing draft. Thus it is removed. If you dont like any of the changes, make sure to PM me.

MOAR SOLER SISTUMS!!!

Name: OGG 788 915W B

Age: 2.3 Billion years

Mass: 2.15 Solar masses

Diameter: 11.5 km

Density: 6.71E+14 g/cm³

Surface Temp.: 20008^o Celcius

Semi-Major Axis: 0.75 AU from the barycenter (Barycenter's SMa is 9901 Light-years.)

Eccentricity of orbit: 0.0

Parent Body: Barycenter

Inclination: 23^o

Type: Visible-light Pulsar (emits violet light BTW.)

Rotation Period: 0.1 seconds

Description: This pulsar is very old, and it's companion is starting to die, and as such is becoming bigger than it's roche lobe, so some of the material has spilled onto this pulsar, converting it's energy into rotational energy and speeding up the pulsar's spin. That means that this pulsar is very inefficient at keeping time, as it's spin is rapidly picking up speed.

 

 

Name: OGG 788 915W A

Age: 2.2 Billion years

Mass: 1.08 Solar masses

Diameter: 0.119 AU

Density: 0.0898 kg/m³

Surface Temp.: 4290^o Celcius

Semi-Major Axis: 1.25 AU from the barycenter

Eccentricity of orbit: 0.0

Parent Body: Barycenter

Inclination: 23^o

Type: Orange giant (Inbetween main sequence and red giant)

Rotation Period: 1.83 years

Description: The reason why this orange giant has the suffix "A" instead of "B" is because it was discovered first, because of it's massive luminosity which flooded the puny light from the pulsar almost competely. OGG 788 915W B was discovered because A had slight variations in it's brightness.

 

Name: OGG 788 915W Ab

Age: 1.9 Billion years

Mass: 0.918 Earth masses

Diameter: 6070 km

Density: 5.85 g/cm³

Surface Temp.: 1536^o Celcius

Semi-Major Axis: 0.278 AU from the barycenter

Eccentricity of orbit: Varies from 0.03-0.29

Parent Body: OGG 788 915W A

Inclination: 23^o

Type: Rocky Sub-Terran

Rotation Period: 51.5 days

Description: This planet is a strange one, as it exists where no planet should, in a close binary system orbiting one star. However, since the pulsar also affects it so often, it has an unstable eccentricity. We believe that this planet will plunge into it's star before the star enters the red giant phase and consumes it's planet and then gets stripped of it's mass faster and faster until it's smaller than it's roche lobe and poofs away until it becomes a red dwarf orbiting the pulsar.
