Investigation of the time structure of the γ-ray burst GRB 080319B
The γ-ray burst GRB 080319B light curve, observed in the energy range from 15 to 350 keV with a 64-ms time resolution by the Swift/BAT mission, has been investigated using a modified method of spectral analysis. The light curve revealed quasi-periodic oscillations with periods from 0.7 to 6 s, in particular, oscillations with constant periods of 0.89 and 1.28 s, independent of the γ-ray energy.
