Periodicities in the X-Ray Intensity Variations of TV Columbae: An Intermediate Polar
نویسندگان
چکیده
We present results from a temporal analysis of the longest and the most sensitive X-ray observations of TV Columbae – a cataclysmic variable classified as an intermediate polar. The observations were carried out with the RossiX − RayT imingExplorer(RXTE) Proportional Counter Array, ROSAT Position Sensitive Proportional Counter, and ASCA. Data were analyzed using a one-dimensional CLEAN and Bayesian algorithms. The presence of a nearly sinusoidal modulation due to the spin of the white dwarf is seen clearly in all Joint Astronomy Programme, Department of Physics, Indian Institute of Science, Bangalore 560 012, INDIA

ASTRONOMY AND ASTROPHYSICS Time - resolved HST and IUE UV spectroscopy of the Intermediate Polar FO Aqr ⋆
Time resolved spectroscopy of the Intermediate Polar FO Aqr reveals the presence of multiple peri-odicities in the UV range. A strong orbital modulation dominates both continuum and emission line flux vari-abilities, while line velocity motions are only detected at the rotational frequency. A prominent orbital periodicity is also observed in coordinated optical photometry, where FO Aqr was prev...
متن کاملThe effects of tidally induced disc structure on white dwarf accretion in intermediate polars
We investigate the effects of tidally induced asymmetric disc structure on accretion onto the white dwarf in intermediate polars. Using numerical simulation, we show that it is possible for tidally induced spiral waves to propagate sufficiently far into the disc of an intermediate polar that accretion onto the central white dwarf could be modulated as a result. We suggest that accretion from th...
متن کاملThe changing accretion states of the intermediate polar MU Camelopardalis
Aims. We study the timing and spectral properties of the intermediate polar MU Camelopardalis (1RXS J062518.2+733433) to determine the accretion modes and the accretion geometry from multi-wavelength, multi-epoch observational data. Methods. Light curves in different observed energy ranges (optical, UV, X-ray) are extracted. The timescales of variability in these light curves are determined usi...
متن کاملSuzaku X-ray Study of an Anomalous Source Xss J12270–4859
We report the results of the Suzaku X-ray observation of XSS J12270–4859, one of the hard X-ray sources in the INTEGRAL catalogue. The object has been classified as an intermediate polar (IP) by optical spectra and a putative X-ray period of ∼860 s. With a 30 ks exposure of Suzaku, we obtained a well-exposed spectrum in the 0.2–70 keV band. We conclude against the previous IP classification bas...
متن کاملRXTE confirmation of the intermediate polar status of IGR J15094--6649
Aims. We aim to establish the X-ray properties of the intermediate polar candidate IGR J15094–6649 and therefore confirm its inclusion into the class. Methods. 42 856 s of X-ray data from RXTE was analysed. Frequency analysis was used to constrain temporal variations and spectral analysis used to characterise the emission and absorption properties. Results. A spin period of 809.7 ± 0.6 s is pre...
