Discovery of the Partially Eclipsing White Dwarf Binary Sdss J143547.87+373338.5 †

Abstract

We have discovered a partially eclipsing white dwarf, low-mass M dwarf binary (3.015114 hour orbital period), SDSS J143547.87+373338.5, from May 2007 observations at the WIYN telescope. Here we present blue band photometry of three eclipses. Eclipse fitting gives main sequence solutions to the M dwarf companion of MS = 0.15 − 0.35M⊙ and RS = 0.17 − 0.32R… (More)
