Deriving an X-ray luminosity function of dwarf novae based on parallax measurements.


Abstract (from CDS):

We have derived an X-ray luminosity function using parallax-based distance measurements of a set of 12 dwarf novae, consisting of Suzaku, XMM-Newton and ASCA observations. The shape of the X-ray luminosity function obtained is the most accurate to date, and the luminosities of our sample are concentrated between ∼1030 and 1031 erg/s, lower than previous measurements of X-ray luminosity functions of dwarf novae. Based on the integrated X-ray luminosity function, the sample becomes more incomplete below ∼3x1030erg/s than it is above this luminosity limit, and the sample is dominated by X-ray bright dwarf novae. The total integrated luminosity within a radius of 200 pc is 1.48x1032 erg/s over the luminosity range of 1x1028 erg/s and the maximum luminosity of the sample (1.50x1032 erg/s). The total absolute lower limit for the normalized luminosity per solar mass is 1.81x1026 erg/s/M which accounts for ∼16 per cent of the total X-ray emissivity of cataclysmic variables as estimated by Sazonov et al.
