  Title: ASCA FIRST OBSERVATION OF SINGLE WOLF-RAYET STAR:VE2-47 (AS268)                 


Abstract:
 We propose to observe SINGLE Wolf-Rayet star Ve2-47 (AS268). Since the launch of
 ASCA, it has already observed 9 Wolf-Rayet stars. But ALL of the 9 WRs are
 Wolf-Rayet BINARY with O-stars. This is because of their excess X-ray luminosities
 caused by the colliding star winds from each of the binary components. Howevwr,
 Einstein observation of galactic Wolf-Rayet stars showed that some of the SINGLE WRs
 are luminous as well as some of the X-ray luminous WR BINARIES, though the SINGLE
 WRs don't have colliding winds. The Einstein observation didn't get the most
 important information---the spectrums. This first ASCA observation of SINGLE WRs
 must make the propaties of them clear for us.
