Title: Orbital Periods for Two Unique, Recently Discovered AM CVn Systems

Abstract: AM CVn systems are rare, ultra-compact binaries which are astrophysical laboratories that allow us to study phenomena including stellar evolution, accretion disk physics, gravitational waves and other aspects of general relativity. They are the He-rich counterparts to cataclysmic variables. We have discovered 7 such systems from Palomar Transient Factory data and here request Gemini time for phase-resolved spectroscopy of two unique systems to find orbital periods. This will provide information towards our goal of understanding the evolution and population distribution of these unique systems.
