METHOD FOR EXTRACTING THE EMISSIONCOMPONENT IN STELLAR SPECTRAL LINES
Keywords:
Stars: atmospheres, Stars: circumstellar matter, Techniques: spectroscopic, Line: profilesAbstract
This article describes a method for separating the contribution of emission components belonging to the stellar envelope from the contribution of stellar photosphere lines in high-resolution spectrograms obtained at the Tusi-Shamakhy Astrophysical Observatory (ShAO). A polynomial approximation method is proposed to account for the instrumental function. Application of this method allows one to separate the emission component belonging to envelope radiation
for different variable stars.
