I am designing a new exoplanet. Do these physical parameters seem plausible?
Sigma Implexis- b is one of three planets orbiting the star called Sigma implexis (S-intertwined), designated a red dwarf star.
Sigma Implexis-b has an annual orbit takes 200 earth days; its daily cycle varies depending on where you are on the planet, the day is slightly longer at the equator because of its ellipsoidal shape. It has three small moons.
Sigma implexis is actually part of a binary star system. The 3 planets and their red dwarf are in a very long elliptical orbit around a blue sun- also a dwarf.
When Sigma Implexis-b and its sun reach the long end of their orbit around the Blue dwarf star, and Sigma Implexis-b gets between the two stars, the planet undergoes “the Bake”.
The Bake can last as long as two Earth weeks. Only in the deepest oceans can the inhabitants survive during the Bake. The Bake only happens once every 450 earth years.
When the Bake happens, most of the polar caps melt, and the seas rise significantly. The continental landmasses are mostly around the equator, and some of the peaks rise as high as the Exosphere on Earth. The air is very thin up there, almost a vacuum.
The volcanism on the planet at the equator affects the magnetic field, and causes some of the atmosphere to be stripped on the upper ranges of the mountains.
The atmosphere is similar to Earth's during its pre-industrial stage, in terms or O2 and CO2 content.
Am I missing anything?
