What is the solar mass of a green star?

Answer 1

There is no such thing as a green star.

I think there are some, but they are uncommon.

Actually, the peak output in the spectrum of our Sun is at green or

yellow-green wavelengths.

However it doesn't look green because we see all the wavelengths together. The result is that the Sun appears white (more or less) apart from atmospheric effects which can make it look red.

(Don't look directly at the Sun, of course.)

As regards the mass of a green star, I suppose that would vary.

It depends on the particular star, just as with blue stars or yellow stars or red stars.
