Outburst and flares from the unique source SWIFT J1955+2614

Popis výsledku v původním jazyce

We present results of our analysis of the optical emission of the unique source GRB 070610/SWIFT J195509+261406 during its 2007 outburst and discuss the implications of the non-detection of the very faint optical counterpart in quiescence. We analyse thestatistical properties of the optical brightness and X-ray intensity during the outburst and determined an approximate value of the mean colour index R-I. The optical emission has the form of spikes whose duration decreases with the outburst's progress,and the spectral energy distribution from the X-ray to the optical bands undergoes variations during the spikes. We show that the optical emission can be explained by a synchrotron mechanism while any thermal component is below the detection limit. We discuss the similarities between synchrotron emission of J1955 and the optical afterglows (OAs) of the extragalactic long gamma-ray bursts. We conclude that while the emission mechanisms in J1955 and OAs are quite similar, the configuratio
