A critical analysis of three near-infrared photometric methods of estimating distances to cataclysmic variables


, : A critical analysis of three near-infrared photometric methods of estimating distances to cataclysmic variables. New Astronomy 17(2): 154-159

A critical analysis of three methods of estimating distances to cataclysmic variables (CVs) is performed. These methods, by Ak et al., Beuermann, and Knigge, all use near-infrared (JHK or Ks) magnitudes and the Barnes-Evans relation. We compare all three methods to distances measured by trigonometric parallax by Thorstensen, with Hubble Space Telescope, and with the HIPPARCOS spacecraft.We find that the method of Ak et al. works best overall for all CVs, predicting distances on the average 4% less than those measured by trigonometric parallaxes. The method of Beuermann overestimates distances by 52%. The method of Knigge underestimates distances by 26%. Highlights: We evaluate 3 methods of estimating distances to cataclysmic variables with parallax distances.
