Eiba posted:Out of curiosity, why do you think it might not be able to? It seems like an overly simplistic result, especially for a planet that has considerable landmass like that one. The oceans would transmit considerable heat compared to solid surface, producing significant regions of snow and ice covered landscape while the oceans remained liquid. The atmosphere would probably be rotating independently of the planet core, leading to a preferential direction of heat transfer, focussed at the equator. There could be issues with maintaining conditions in which the water at the stellar maxima isn't cold enough to freeze, or hot enough to evaporate into major cloud cover, both of which could force albedo cooling, though that would depend somewhat on the spectral output of the parent star.

Looks like the orbital tracks for the comets around a star. The circles would be the orbits of the planets.

Yeah, the best/only way to simulate a universe is to construct said universe. Far easier to only simulate the bits you're interested in at the fine level and fudge the rest.

Contact binary asteroids are a thing, so that moon isn't totally absurd as a captured object. Assuming it is one object. Contact binary stars are also a thing.

Bubbacub posted:I found a "scorched ice giant" that's basically skimming the surface of its star. Not sure what kind of ice can survive those 1800 K temperatures... "Ice giant" is a bit of a misnomer. In this context (astronomers love to redefine common words) "ice" is being used to emphasise that a large fraction of the object is made up of substances that form ices (water, methane, ammonia etc) rather than just hydrogen and helium.
