7. It's not in our solar system--the article says the yellow dwarf is 285 light years away.

I actually have some doubt as to whether a companion star such as a brown dwarf could be in the same solar system as the yellow dwarf. My thoughts behind that are that the orbital time period of the gas giant would vary because of the gravitational effects which wasn't mentioned in the excerpt.

Our thoughts are pretty much in a line with my suggestion of a rogue planet being captured when passing close to the dwarf star rather than an entire solar system. It just seems easier to capture one planet versus an entire solar system.

Possibly a rogue planet that was caught into the red dwarf's gravity well? TexasTowelie Feb 2023 #3
