Cyclotron Line Variability

Tatehiro Mihara, Kazuo Makishima, Fumiaki Nagase

We systematically analyzed the spectra of X-ray binary pulsars observed with GINGA (Mihara 1995). A new model NPEX (Negative and Positive power-laws EXponential) was introduced t o…

Broad band X-ray spectroscopy of A0535+262 with SUZAKU

S. Naik, T. Dotani, Y. Terada +9

The transient X-ray binary pulsar A0535+262 was observed with Suzaku on 2005 September 14 when the source was in the declining phase of the August-September minor outburst. The ~10…

Suzaku Observations of Hercules X-1 : Measurements of the Two Cyclotron Harmonics

Teruaki Enoto, Kazuo Makishima, Yukikatsu Terada +10

The accretion-powered pulsar Her X-1 was observed with Suzaku twice in its main-on state, on 2005 October 5-6 and 2006 March 29-30, for a net exposure of 30.5 ks and 34.4 ks, respe…

X-ray Spectral Study of the Photoionized Stellar Wind in Vela~X-1

Shin Watanabe, Masao Sako, Manabu Ishida +6

We present results from quantitative modeling and spectral analysis of the high mass X-ray binary Vela X-1 obtained with the Chandra HETGS. The spectra exhibit emission lines from…

ASCA Observations of OAO 1657-415 and its Dust-Scattered X-Ray Halo

Michael D. Audley, Fumiaki Nagase, Kazuhisa Mitsuda +2

We report on two ASCA observations of the high-mass X-ray binary pulsar OAO 1657-415. A short observation near mid-eclipse caught the source in a low-intensity state, with a weak c…

Ionization States and Plasma Structures of Mixed-morphology SNRs Observed with ASCA

Masahiro T. Kawasaki, Masanobu Ozaki, Fumiaki Nagase +2

We present the results of a systematic study using ASCA of the ionization state for six ``mixed-morphology'' supernova emnants (MMSNRs): IC 443, W49B, W28, W44, 3C391, and Kes 27.…
