Recent Chandra studies have confirmed that globular clusters can indeed harbor multiple transients and that more quiescent LMXBs are hiding under the sensitivity limits of even relatively deep Chandra exposures. Both findings have significant implications for studies of accreting neutron stars and have provided better insight into globular cluster compact binary populations. Here we propose a Chandra program to precisely localize new transients in globular clusters. As part of this effort we further request HST observations to identify the optical counterparts of these transients. All team members have extensive expertise in Chandra data analysis and are experts on (transient) X-ray sources in globular clusters. They all have led past Chandra observations of globular clusters. Dr. Heinke and Dr. Homan have studied and modeled crustal cooling or accretion heated neutron stars. Dr. Homan and Dr. Pooley will lead the analysis of the Chandra data. Dr. van den Berg has extensive expertise with the analysis of HST observations and will lead the analysis of the HST data. All team members will contribute to the interpretation of the data and publishing of the results.
