Abstract

HETE-2 (High Energy Transient Explorer-2) has made remarkable observations of gamma-ray bursts (GRBs) since HETE-2 was launched in October, 2000. HETE-2 can perform the prompt notification of gamma-ray bursts with onboard computer and ground receiving system. The concept of data processing system of HETE-2 is contrived to follow a short bursting astronomical objects such as gamma-ray bursts. HETE-2 is the first small satellite which has achieved a prompt alert system of gamma-ray burst locations calculated by onboard computer. Thus researchers of gamma-ray bursts can access the accurate location of bursts observed with HETE-2 through internet. HETE-2 has observed many gamma-ray bursts alerted their locations; i.e., a few to several bursts every month. Thus, optical, radio and X-ray observatories have made follow-up observations promptly. As a result a considerable number of optical transients are discovered and then their detailed observations are made. In this paper we report a unique concept of HETE-2, a gamma-ray observation satellite and some remarkable results obtained by HETE-2.
