Of course the "now" planet could have been more massive, perhaps a brown dwarf or low mass star? The initial orbit was of course further out and friction from interacting with the red giant atmosphere led to orbital decay.helicon wrote: ↑Wed Dec 04, 2019 9:00 pm One wonders how the planets orbiting this star would have withstood the changes when it went through its red giant phase. Seemingly they would have been vaporized. Somehow one giant planet survived and it is even larger than its host star, and moved into an orbit that is so close that it is astounding. Fascinating stuff notFritz!
