George,

So, that subset must be equal to around 150 stars? Since 45/150 X 100= 30%. But it said in Greg Laughlin's post that 400 stars were non-active FGK type stars. Why then, if they are non-active, were 250 stars excluded from analysis?

In the article it says that 10% of sun-like stars have hot-Jupiters (jovians closer to their stars than Mercury is to the Sun), but only 1% have planets of this size and orbital separation.

I can't help but think that something is wrong with the information presented in this article...
