Towards 4U1630−47: a black-hole soft X-ray transient odyssey
نویسنده
چکیده
4U1630−47 is a black-hole X-ray transient with one of the shortest recurrence times. Despite its regular outburst behaviour little is known about this source. Only recently has attention to this system increased. I discuss there the basic known (X-ray) properties of 4U 1630−47 and report on X-ray and radio observations obtained during its recent outburst, starting in 1998 February. These observations strengthen some of the similarities seen between 4U 1630−47 and the Galactic superluminal sources GROJ1655−40 and GRS1915+105, and provide the first detection of 4U1630−47 in the radio. Using an updated outburst ephemeris I predict the next outburst to occur about a week before Christmas 1999.

We have re-analyzed two EXOSAT Medium Energy observations during part of the 1984 X-ray outburst of the black-hole candidate transient system 4U1630−47. One observation (May 10) shows fast timing properties (on timescales shorter than ∼250 s) typical of those of other black hole candidates in their high states. The power-spectrum shows a power law with index ∼0.7 and fractional rms amplitude (0...
متن کاملThe 1998 outburst of the X-ray transient 4U 1630–47 observed with BeppoSAX
We report results of five pointed BeppoSAX observations of the black hole candidate 4U1630–47 during part of its 1998 outburst when the 2–10 keV source luminosity decreased from 2.1×10 erg s (for an assumed distance of 10 kpc) by a factor of ∼7. The 2–200 keV spectrum can be modeled by a soft multi-temperature disk blackbody and a hard power-law. During four of the observations, there is eviden...
متن کاملThe Off State of GX 339 – 4
We report BeppoSAX and optical observations of the black hole candidate GX339– 4 during its X-ray ‘off’ state in 1999. The broad-band (0.8–50 keV) X-ray emission can be fitted by a single power law with spectral index, α ∼ 1.6. The observed luminosity is 6.6 × 10 erg s in the 0.5–10 keV band, which is at the higher end of the flux distribution of black hole soft X-ray transients in quiescence, ...
متن کاملA search for the IR counterpart of the black hole candidate 4 U 1630 - 47
We present the first attempt to localize the IR counterpart of the recurrent, ultra soft X-ray transient 4U 1630-47. We have obtained two sets of K band images of this highly obscured region, during both outburst and quiescence. The recent radio position reported by Hjellming et al. (1999) allow us to perform accurate astrometry on the field. We discuss three stars which lie near the radio posi...
متن کاملInclination Effects and Beaming in Black Hole X-ray Binaries
We investigate the dependence of observational properties of black hole Xray binaries on the inclination angle i of their orbits. We find the following: (1) Transient black hole binaries show no trend in their quiescent X-ray luminosities as a function of i, suggesting that the radiation is not significantly beamed. This is consistent with emission from an accretion disk. If the X-rays are from...
