Orbital periods of cataclysmic variables identified by the SDSS. VI. The 4.5-hr period eclipsing system SDSS J100658.40+233724. (2009)

Abstract:We present time-resolved spectroscopy and photometry of SDSS J100658.40+233724.4, which we have discovered to be an eclipsing cataclysmic variable with an orbital period of 0.18591324 days (267.71507min). The observed velocity amplitude of the secondary star is 276+/-7km/s, which an irradiation correction reduces to 258+/-12km/s. Doppler tomography of emission lines from the infrared calcium triplet supports this measurement. We have modelled the light curve using the LCURVE code and Markov Chain Monte Carlo simulations, finding a mass ratio of 0.51+/-0.08. From the velocity amplitude and the light curve analysis we find the mass of the white dwarf to be 0.78+/-0.12M_{sun}_ and the masses and radii of the secondary star to ...(more)

We present the discovery and follow-up observations of eclipses of the cataclysmic variable star SDSS J100658.40+233724.4, fom which we determine the orbital period and the masses and radii of the two stellar components. Time-resolved optical spectroscopic observations covering the full orbital period were obtained on three consecutive nights. Time-resolved photometry of four eclipses was obtained between 2008 February and December.
