Talk:CS Gru

Exerpt of Michael email from 2006-09-15.

CS Gru's Li is very strong. Unfortunately one cannot really estimate its (young?) age, as its is a rather early spectral type. G8 sometimes have Li still for older ages, and therefore it is difficult to say that this is a generic TTS. Maybe rather an post-TTS, sometimes called "yellow excess star".... Apparently it is a bright ROSAT X-ray source and hence even enhance its likelihood for being young.

These guys say its of BY Dra type. (But those are mostly fishy classifications). No signs of being SB2, or binary.

So, not a paper on its own, but worth a remark.
