Hard X-ray properties of magnetic cataclysmic variables
Hard X-ray surveys have proven remarkably efficient in detecting intermediate polars and asynchronous polars, two of the rarest type of cataclysmic variable (CV). Here we present a global study of hard X-ray selected intermediate polars and asynchronous polars, focusing particularly on the link between hard X-ray properties and spin/orbital periods. To this end, we first construct a new sample ...
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 کاملTwo Types of X-ray Spectra in Cataclysmic Variables
We present Chandra HETG spectra of seven cataclysmic variables. We find that they divide unambiguously into two distinct types. Spectra of the first type are remarkably well fit by a simple cooling flow model, which assumes only steady-state isobaric radiative cooling. The maximum temperature, kTmax, and the normalization, which provides a highly precise measurement of the accretion rate, are t...
متن کاملProperties of the Galactic population of cataclysmic variables in hard X - rays
We measure the spatial distribution and hard X-ray luminosity function of cataclysmic variables (CVs) using the INTEGRAL all-sky survey in the 17–60 keV energy band. The vast majority of the INTEGRAL detected CVs are intermediate polars with luminosities in the range 10–10 erg s. The scale height of the Galactic disk population of CVs is found to be 130 −50 pc. The CV luminosity function measur...
متن کاملThe EUV and X-ray Emission of Nonmagnetic Cataclysmic Variables
Recent results are presented and discussed regarding the EUV and X-ray emission of nonmagnetic cataclysmic variables. Emphasis is given to high accretion rate systems (novalike variables and dwarf novae in outburst), and to a number of apparent discrepancies between observations and the theory of the boundary layer between the accretion disk and the surface of the white dwarf. Discussed are EUV...
