Scientific paper

AM CVn's are extremely rare double-degenerate cataclysmic variables, perhaps including the shortest-period binaries known. They are of high interest as possible supernova progenitors, and future sources of detectable gravity waves. We have discovered 3 new AM CVn candidates in the Sloan Digital Sky Survey, providing a significant expansion to the sample-size for this elite sublcass. We propose initial Chandra X-ray detections and flux measures, which will provide constraints on their mass accretion rates. These are important for understanding evolutionary aspects that test the interplay between mass-transfer and gravitational radiation. We would also be able to sensitively assess viability, and plan for more detailed follow-on X-ray timing and/or X-ray spectroscopy studies.
