Abstract

Tidal disruptions of stars by super‐massive black holes are one of the most spectacular phenomena that can occur in the Galactic center. Studying this process can give us much information on the black hole itself, the environment around it, and the growth and evolution of super‐massive black holes. Here we consider different types of stars in calculating physical quantities during tidal disruptions and apply our results to three astrophysical problems: X‐ray flares in normal galaxies, TeV gamma‐ray emissions from our Galactic center and the growth of the black holes harbored in the centers of galaxies, which grow solely through capturing stars even if they never experienced other modes of mass growth.
