Fourier analysis of rotationally broadened stellar spectra.
Abstract
A complex combination of physical processes affecting mainly the shape of a spectral line formed in stellar atmosphere can be better distinguished at low Fourier frequencies than in the profile itself. Considering the analysis of stellar rotationally broadened line as a typical example of those astrophysical problems where it is more advantageous to use the Fourier transform of the profile, the author presents a method for determination of stellar projected rotational velocity and limb-darkening coefficient.
