Accretion in Cataclysmic Variable Stars
We consider accretion onto the white dwarfs in cataclysmic variables in relation to nova eruptions, dwarf nova outbursts, hibernation and non-radial oscillations.
متن کاملX-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 کاملThe Neutron Stars of Soft X–Ray Transients
Soft X–ray Transients (SXRTs) have long been suspected to contain old, weakly magnetic neutron stars that have been spun up by accretion torques. After reviewing their observational properties, we analyse the different regimes that likely characterise the neutron stars in these systems across the very large range of mass inflow rates, from the peak of the outbursts to the quiescent emission. Wh...
متن کاملTHE CHANDRA X-RAY OBSERVATORY Observations of Neutron Stars
We present here an overview of the status of the Chandra X-ray Observatory which has now been operating for five years. The Observatory is running smoothly, and the scientific return continues to be outstanding. We provide some details on the molecular contamination of the ACIS filters and its impact on observations. We review the observations with Chandra of the pulsar in the Crab Nebula and a...
