    X-ray Observation of Black Hole Novae

    X-ray novae are the best objects to study their compact stars. Some of the X-ray novae have been confirmed that they were containing a black hole based on dynamical mass estimations. Besides the dynamical mass...

    Direct Measurement of the CCD with a Subpixel Resolution by Using a New Technique

    The response function of the front-illuminated CCD, like SIS on ASCA, can be devided into three parts: the gate structure transmission, the absorption efficiency in the depletion region and the charge spreadin...

    X-Ray Determination of the Black-Hole Mass in Cygnus X-1

    About 10 X-ray binaries in our Galaxy and LMC/SMC are considered to contain black hole candidates (BHCs). Among these objects, Cyg X-l was identified as the first BHC, and it has led BHCs for more than 25 year...

    The Circumstellar Matter of Cygnus X-3

    X-ray source in Cyg X-3 is embedded in the photo-ionized circumstellar gas. Recombination edges and emission lines were detected by ASCA observation (Kawashima, Kitamoto 1996; Liedahl, Paerels 1996). The stren...

    Chemical Abundances of Early Type Stars

    X-rays from early-type stars are emitted by the corona or the stellar wind. The materials in the surface layer of early-type stars are not contaminated by nuclear reactions in the stellar inside. Therefore, ab...

    Temperature Profiles of Accretion Disks in X-Ray Binaries

    We present the new results of fitting X-ray spectra of two representative X-ray binaries; X-ray Nova Muscae 1991 and Cyg X-2, by a non-steady disk model, in which a temperature gradient, a ≡ — dlogT/dlogr, is lef...
