  1. PTF1 J071912.13+485834.0: An Outbursting AM CVn System Discovered by a Synoptic Survey

    Levitan, David; Fulton, Benjamin J.; Groot, Paul J.; Kulkarni, Shrinivas R.; Ofek, Eran O.; Prince, Thomas A.; Shporer, Avi; Bloom, Joshua S.; Cenko, S. Bradley; Kasliwal, Mansi M.; Law, Nicholas M.; Nugent, Peter E.; Poznanski, Dovi; Quimby, Robert M.; Horesh, Assaf
    We present extensive photometric and spectroscopic observations of PTF1 J071912.13+485834.0, an outbursting AM CVn system discovered by the Palomar Transient Factory (PTF). AM CVn systems are stellar binaries with some of the smallest separations known and orbital periods ranging from 5 to 65 minutes. They are believed to be composed of a white dwarf accretor and a (semi-)degenerate He-rich donor and are considered to be the helium equivalents of cataclysmic variables (CVs). We have spectroscopically and photometrically identified an orbital period of 26.77 ± 0.02 minutes for PTF1 J071912.13+485834.0 and found a super-outburst recurrence time of greater than 65 days...
