EinsteinLX&LBLValuesforIPCOStars
Soft X-ray (0.2 - 3.5 keV) measurements for all normal, massive, o-type stars surveyed with the Einstein Observatory are presented as a catalog containing 89 detections and 176 upper bounds, together with a detailed discussion of the reduction process. Values of L[x]/L[bol] listed for most stars, range from 10e-5.44 to 10e-7.35; l[x] spans more than 3 orders of magnitude, ranging from 1.5 x 10e31 to 2 x 10e34 ergs se-1. It is noted that at least 30% of o-type stars are variable in X-rays, but that there is little evidence for new objects whose X-ray emission might be significantly enhanced by accretion processes onto a neutron star. For further information, please contact the HEASARC. This is a service provided by NASA HEASARC .
