The Activity of the Soft Gamma Repeater SGR~1900+14 in 1998 from Konus-Wind Observations: 1. Short Recurrent Bursts

Abstract

Results are presented of the observations of the soft gamma repeater SGR 1900+14 made on the Wind spacecraft during the source reactivation period from May 1998 to January 1999. Individual characteristics of recurrent bursts, such as their time histories, energy spectra, and maximum and integrated energy fluxes, are considered. Some statistical distributions and relationships are also presented. The close similarity of these events to the recurrent bursts observed from other SGRs argues for a common emission mechanism.
