The Eclipsing Black Hole X - ray Binary M 33 X - 7 : Understanding the Current Properties
We explore the formation and evolution of the black hole X-ray binary system M33 X-7. In particular, we examine whether accounting for systematic errors in the stellar parameters inherent to single star models, as well as the uncertainty in the distance to M33, can explain the discrepancy between the observed and expected luminosity of the ∼ 70M⊙ companion star. Our analysis assumes no prior in...
متن کاملX - ray transient and eclipsing binary X 1658 – 298
We report the discovery of nearly coherent oscillations with a frequency of ∼ 567 Hz during type-I X-ray bursts from the X-ray transient and eclipsing binary X 1658–298. If these oscillations are directly related to the neutron star rotation then the spin period of the neutron star in X 1658–298 is ∼1.8 ms. The oscillations can be present during the rise or decay phase of the bursts. Oscillatio...
متن کاملThe Eclipsing Supersoft X-ray Binary Cal 87
We present and discuss 25 spectra obtained in November 1996, covering all phases of the CAL 87 binary system. These spectra are superior both in signal-to-noise and wavelength coverage to previously published data so that additional spectral features can be measured. Photometry obtained on the same nights is used to confirm the ephemeris and to compare with light curves from previous years. Ana...
متن کاملSimultaneous optical polarimetry and X-ray observations
CP Tuc (AX J2315–592) shows a dip in X-rays which lasts for approximately half the binary orbit and is deeper in soft X-rays compared with hard X-rays. It has been proposed that this dip is due to the accretion stream obscuring the accretion region from view. If CP Tuc was a polar, as has been suggested, then the length of such a dip would make it unique amongst polars since in those polars in ...
