Keywords: Sun, solar-like stars, surface gravity, rotation velocity, gravitational constant
The evaluation of stars' properties is classically performed by comparing the stars' light spectra and fluxes to the known solar properties. Another method to find the stars' rotation velocity will be discussed here: the extrapolation to the other solar-like stars of an empiric solar property, which consists of a direct relationship between the star's frequency and its surface gravity, without the need of any other parameters.
