Scientific paper

Correlations are drawn between the temporal and spectral behavior of gamma-ray bursts detected during 1978-80 in the Konus experiment with the Venera 13 and 14 spacecraft. The data were gathered with photomultiplier tubes functioning in the 150-700 and 40-180 keV ranges, providing time profiles of the events with 0.25 sec resolution. Data were also available from the Solar Maximum Mission spacecraft. Attention is given to the evolution of the energy spectra time profiles. A strong correlation is found between the instantaneous luminosity and the temperature for the range of variation of the temperature 100-1000 keV. The results indicate that the flow of energy to the emitting region probably controls the spectral variability and therefore the time profile of the bursts.
