Hello
How can I determinate the inhabitable zone of a star

Have you looked here?

There's some information on this here:

Just glancing through it quickly, I didn't see any formulas you can simply plug values into, but I'm sure there are some around. (Will keep looking)

It's probably not very simple, since you would have to take the spectral type of the star in consideration.

Nothing in (or about) life is simple!

Naturally I didn't mean to imply it would be simple, only that there must be ways of determining the habitable zone for a given star. The operant concept seems to be the range at which water can exist. Various factors (stellar spectral type (F, G, K), size, age and stability; planetary mass, atmosphere, land/water surface ratio, presence/absence of large moons, eccentricity of planetary orbit) play a role.

A bit more searching turned up some actual calculation methods at

There's a lot of information out there, so it'll take some time to find what you want, but where there's a will....

I'm sorry. I didn't mean to imply you'd think it were to be simple.
I was just thinking out loud.

This picture comes from a nice educational simulation game (web-based) there:
