XMM-Newton and Chandra observations of the ultra-compact binary RX J1914+24.

RAMSAY G., CROPPER M. and HAKALA P.

Abstract (from CDS):

The nature of the X-ray source RX J1914+24 has been the subject of much debate. It shows a prominent period of 569 s in X-rays and the optical/infrared: in most models this has been interpreted as the binary orbital period. We present our analysis of new XMM-Newton and Chandra data. We find a longer term trend in the XMM-Newton data and power at 553 and 584 s in five sets of data. It is not clear if they are produced as a result of a beat between a longer intrinsic period and the 569-s modulation or if they are due to secular variations. We obtain a good fit to the XMM-Newton spectrum with a low-temperature thermal plasma model with an edge at 0.83 keV. This model implies an unabsorbed bolometric X-ray luminosity of 1 x 1033erg/s (for a distance of 1 kpc) - this is 2 orders of magnitude lower than our previous estimate (derived using a different model). If the distance is much less, as the absorption derived from the X-ray fits suggest, then the X-ray luminosity is even lower at ∼ 3x1031erg/s.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
