The photospheric temperature and metal abundance of the compact star H 1504+65.
Barstow, M. A.; Tweedy, R. W.
A new analysis of an Exosat low-energy telescope observation of the hot compact star H1504 + 65 is presented. Earlier results had failed to take into account the large point-spread function produced by the boron filter, and hence the count rate had been underestimated by a large factor. On comparing the data with a new grid of model atmospheres co…
Gamma rays from dark clouds.
Feitzinger, J. V.; Stuewe, J. A.
The distribution of dark clouds and the COS-B X-ray observations of the local interstellar medium at intermediate galactic latitudes are compared. The dark cloud catalog of Lynds (1962) is combined with the complementary work of Feitzinger & Stuewe (1986) to obtain a uniform coverage of the medium-latitude sky. A good correlation between the e…
