摘要:
RecentRXTEobservations of the SMC have revealed two previously unknown transient X-ray pulsars with pulse periods of 95s and 4.78s. The sources are proposed as Be/neutron star systems on the basis of their pulsations, transient nature and characteristically hard spectra. Optical observations indicate an H&agr; emission-line star as a candidate optical counterpart. These results add to the emerging picture of the SMC as containing an extremely dense population of transient HMXBs, only a fraction of which are active at any one time. ©2001 American Institute of Physics.
