description: This master thesis is devoted to the study of spectral evolution of bright short gamma-ray bursts (GRBs) detected by the Fermi-GBM. Using the sample of six bright Fermi short-duration GRBs the burst light curves and spectra were analyzed. As a result only one burst shows hardness-intensity correlation, while the rest do not show such behavior. This work also contains some general information about gamma-ray bursts and the Fermi space observatory; it contains information about other modern gamma-ray burst observatories, techniques of gamma-ray burst spectral analysis and the most commonly used gamma-ray burst spectrum models. The novelty of this work lies in the fact that no one has yet performed a de-tailed analysis of spectral evolution of GRBâ111222A, GRB 120323A, GRB 130310A, GRB 150819B, GRB 170127C, GRB 181222B. The spectral analysis of the six most intense short gamma-ray bursts registered by the Fermi-GBM will help to better understand physics of short gamma-ray bursts.
