Abstract (from CDS):

The short/hard GRB 051210 was detected and located by the Swift-BAT instrument and rapidly pointed towards by the narrow field instruments. The XRT was able to observe a bright, rapidly fading X-ray emission. We present the analysis of the prompt and afterglow emission of this event. The BAT spectrum is a power-law with photon index 1.0±0.3. The X-ray light curve decays with slope -2.58±0.11 and shows a small flare in the early phases. The spectrum can be described with a power law with photon index 1.54±0.16 and absorption (7.5–3.2+4.3)x1020cm–2. We find that the X-ray emission is consistent with the hypothesis that we are observing the curvature effect of a GRB that occurred in a low density medium, with no detectable afterglow attributable to an external shock. We estimate the density of the circumburst medium to be lower than 3x10–3cm–3. We also discuss different hypothesis on the possible origin of the flare.
