PPT-Searching for Planets Around White Dwarfs

J Ellis Department of Astronomy University of Texas Austin TX 78712 USA White dwarfs are remnants of stars that have depleted all fusible resources 97 of stars end their lives as white dwarfs. A Davenport Astronomy 521 2010 Term Paper Abstract Since M dwarfs comprise 75 of the stars in our galaxy including many nearby stars they may be a critical location to search for habitable planets Classically these systems have been thought to be in Extra-solar planetary systems.
