Exploring the Habitable Zone and Tidal Lock in Exoplanet Systems

[Freight_train04]

I am new and would like some help. I have two questions for a shout out.

1) I need some info to help detirmine the Habitable Zone of a paticular star. I think that JF Kasting propsed some kind of equation but I can't find anymore info on it. I don't really need the equation per say just data on the breadth of the HZ and its distance from the star. I need info for all classes F to M.

2)Along the same lines. When talking about habitablilty around M class stars the subject of tidal lock comes up. Is there an equation to represent under what circumstances this could occur. (Again, I don't accually need the equation if there is a general rule of thumb or published data table.)

Thanks for your help.
