Re: Rather a lot of unanswered questions there
Our current understanding of low density planets is that they're a *lot* of gas around a smallish rocky core, though at Jupiter-ish sizes there's likely some crazy pressure-related shit going on with metallic, liquid, hydrogen. This one isn't anywhere near to Jupiter scales so it's probably just rocks.
So it's losing all the gas and as the article states it'll eventually end up with just the rocky core.
