[54.01] GRBs from HETE: Recent Results and Future Prospects

G.R. Ricker, N.R. Butler (MIT), and the HETE Team

The High Energy Transient Explorer (HETE) is the first satellite mission devoted to the study of gamma-ray bursts (GRBs). HETE utilizes a matched suite of wide-field gamma-ray and X-ray detectors mounted on a small spacecraft in an equatorial orbit. A unique feature of HETE is its potential for localizing GRBs with sub-arcminute accuracy, and disseminating the localizations promptly (~seconds to ~minutes), often as the burst is still in progress.

HETE continues to detect ~80 GRBs per year, of which it localizes ~20 per year. As of March 2003, HETE had localized 33 GRBs; nine localizations had led to the detection of an X-ray, optical, or radio afterglow; seven GRBs had established redshifts. In this paper, we will present recently-discovered GRBs from the past six months of HETE operations, and discuss the properties of the prompt gamma and X-ray emission of particularly interesting HETE bursts (including GRB021004).

The HETE scientific team includes participants from France, Japan, Brazil, India, Italy, and the USA. This research was supported in the USA by NASA contract NASW-4690.
