| Summary: | In this catalog, we present the results of a systematic study of 199 short
gamma-ray bursts (GRBs) detected by Konus-Wind between 2011 January 1 and 2021
August 31. The catalog extends the Second Catalog of short gamma-ray bursts
covering the period 1994-2010 by ten years of data. The resulting Konus-Wind
short GRB sample includes 494 bursts. From temporal and spectral analyses of
the sample, we provide the burst durations, spectral lags, estimates of the
minimum variability time scales, rise and decay times, the results of spectral
fits with three model functions, the total energy fluences, and the peak energy
fluxes of the bursts. We present statistical distributions of these parameters
for the complete set of 494 short gamma-ray bursts detected in 1994-2021. We
discuss evidence found for an additional spectral component and the presence of
extended emission in a fraction of the short GRBs. Finally, we consider the
results in the context of the Type I (merger-origin)/Type II (collapsar-origin)
classification, and discuss magnetar giant flare sub-sample. |
