Title: The Primary Mass of a New Candidate of Quiescent Low-Mass X-ray Binary
Abstract: We propose to complete the project we started in year 2011 - to explore a new method in searching for qLMXBs in their quiescent states. We propose to use the CTIO 1.5m and 1.3m to complete this project. Our target is a new candidate qLMXB with a plausible orbital period of ~2.42 days. We propose to measure its radial velocity using the CTIO 1.5m, and obtain more photometry data using the CTIO 1.3m to accurately measure its orbital period and inclination, and therefore determine its mass function. If confirmed, it will be the first qLMXB ever discovered in quiescent state and in a targeted survey. This will open the door to a new way to search for accretion binaries hidden in the Galaxy. We ask a minimum telescope time for a possible very high scientific return.
