Global Characteristics of X-Ray Flashes and X-Ray-Rich GRBs Observed by HETE-2
T. Sakamoto, D. Q. Lamb, C. Graziani +35
We describe and discuss the global properties of 45 gamma-ray bursts (GRBs) observed by HETE-2 during the first three years of its mission, focusing on the properties of X-Ray Flas…
Highlights of the HETE-2 Mission
D. Q. Lamb, G. R. Ricker, J. -L. Atteia +37
The HETE-2 mission has been highly productive. It has observed more than 250 GRBs so far. It is currently localizing 25 - 30 GRBs per year, and has localized 43 GRBs to date. Twent…

HETE-2 Observations of the Extremely Soft X-Ray Flash XRF 020903
T. Sakamoto, D. Q. Lamb, C. Graziani +36
We report HETE-2 WXM/FREGATE observations of the X-ray flash, XRF 020903. This event was extremely soft: the ratio log(S_X/S_gamma) = 0.7, where S_X and S_gamma are the fluences in…
HETE-2 Localization and Observation of the Bright, X-Ray-Rich Gamma-Ray Burst GRB021211
G. B. Crew, D. Q. Lamb, G. R. Ricker +35
A bright, x-ray-rich GRB was detected by HETE-2 at 11:18:34.03 UT on 11 Dec 2002. The WXM localization was to 14' and relayed to the GCN 22 s after the start of the burst. The grou…
GRB010921: Localization and Observations by the HETE Satellite
G. Ricker, K. Hurley, D. Lamb +36
On September 21 at 18950.56 SOD (05:15:50.56) UT the FREGATE gamma-ray instrument on the High Energy Transient Explorer (HETE) detected a bright gamma-ray burst (GRB). The burst wa…
