X-ray Variability of the Magnetic Cataclysmic Variable V1432 Aql
V1432 Aquilae (=RX J1940.2−1025) is the X-ray bright, eclipsing magnetic cataclysmic variable ∼37 away from the Seyfert galaxy, NGC 6814. Due to a 0.3% difference between the orbital (12116.3 s) and the spin (12150 s) periods, the accretion geometry changes over the ∼50 day beat period. Here we report the results of an RXTE campaign to observe the eclipse 25 times, as well as Also Universities ...
متن کاملRecent Advances in X-ray Observations of Cataclysmic Variables
A personal selection of noteworthy X-ray results on CVs are presented, with emphasis on XMM-Newton and Chandra observations. Progressing roughly from broad-band view to narrow-band, high spectral resolution studies, I summarize: the energy balance of polars; X-ray confirmation of IPs; eclipses in non-magnetic CVs; search for magnetism in " non-magnetic " CVs; multi-temperature plasma emission f...
متن کاملX-ray Spectroscopy of Cataclysmic Variables
In cataclysmic variables (CVs), accretion onto white dwarfs produces high temperature, high density plasmas. They cool down from kT∼10 keV via bremsstrahlung continuum and K and L shell line emissions. The small volume around white dwarfs means that the plasma densities are much higher than in, e.g., stellar coronae, probably beyond the range well-described by existing models. I will describe p...
متن کاملChandra observations of the millisecond X – ray pulsar IGR J 00291 + 5934 in quiescence
In this Paper we report on our analysis of three Chandra observations of the accretion– powered millisecond X–ray pulsar IGR J00291+5934 obtained during the late stages of the 2004 outburst. We also report the serendipitous detection of the source in quiescence by ROSAT during MJD 48830–48839 (July 26–August 4, 1992). The detected 0.3–10 keV source count rates varied significantly between the C...
متن کاملXMM - Newton observations of the INTEGRAL X - ray transient IGR J 17544 − 2619
On 2003 September 17 INTEGRAL discovered a bright transient source 3◦ from the Galactic Center, IGRJ17544−2619. The field containing the transient was observed by XMM-Newton on 2003 March 17 and September 11 and 17. A bright source, at a position consistent with the INTEGRAL location, was detected by the European Photon Imaging Camera (EPIC) during both September observations with mean 0.5–10 k...
