X-Ray Afterglow Sources from Gamma-Ray Bursts

E. Costa (IAS/CNR, Rome)

Since 1996 BeppoSAX is pointing the positions o Gamma-Ray Bursts as derived from Wide Field Camera detections and, in fewer cases, from other missions. Several Afterglow Sources have been detected and studied, also with the important contribution of other satellites. The temporal, spectral properties of these afterglow sources are reviwed, and, as far as possible, correlated with the X/Gamma properties of the prompt burst, and with the information derived in other energy bands.
