Hot Jupiters from mergerers - Implications for blue stragglers

Post by Sirius_Alpha on 27th February 2011, 11:21 pm

An interesting look at the idea of hot Jupiter formation from the merging of a tight binary with implications for blue stragglers.

HR 8799 neither has any known hot Jupiters, nor is it a blue straggler.

Steinn Siguršsson of Dynamics of Cats has written about the possibility of HR 8799 being a blue straggler on the blog, e.g. here.

Dynamics of Cats says it's a Type I Blue Straggler.

There's a Type I kind?
Are there any others?
