X-ray and ultraviolet observations of the eclipsing cataclysmic variables OV Bootis and SDSS J103533.02+055158.3 with degenerate donors
Axel Schwope, Hauke Worpel, Iris Traulsen
The majority of cataclysmic variables are predicted to be post-period minimum systems with degenerate donor stars, the period bouncers. Owing to their intrinsic faintness, however,…
The various accretion modes of AM Herculis: Clues from multi-wavelength observations in high accretion states
A. D. Schwope, H. Worpel, I. Traulsen +1
We report on XMM-Newton and NuSTAR X-ray observations of the prototypical polar, AM Herculis, supported by ground-based photometry and spectroscopy, all obtained in high accretion…
XMM-Newton observations of eleven intermediate polars and possible candidates
Hauke Wörpel, Axel Schwope, Iris Traulsen +2
We aim to identify new intermediate polars (IPs) in XMM-Newton observations from a list of promising candidates. By selecting targets not previously known to be X-ray bright we aim…
Identification of 3XMM J000511.8+634018 as a new polar at P(orb)=133.5 min -- is it inside or outside the period gap?
A. D. Schwope, H. Worpel, N. A. Webb +2
We aimed to identify the variable X-ray source 3XMM J000511.8+634018, which was serendipitously discovered through routine inspections while the 3XMM catalogue was compiled. We ana…
The Influence of Stellar Spin on Ignition of Thermonuclear Runaways
Duncan K. Galloway, Jean J. M. in 't Zand, Jérôme Chenevez +7
Runaway thermonuclear burning of a layer of accumulated fuel on the surface of a compact star provides a brief but intense display of stellar nuclear processes. For neutron stars a…
Identification spectra of several Northern Hemisphere CV candidates
H. Worpel, A. D. Schwope
We obtained Calar Alto identification spectra for six cataclysmic variable candidates, and studied archival observations at a range of wavelengths. Two sources were too faint to al…
