SUMMARY OF SEQUENCE NUMBER 400087

Title: BRIGHT LMXB GLOBULAR CLUSTER SURVEY: NATURE, MASSES AND CLUSTER DYNAMICS

Observer: Edmonds

Subject Category: BH and NS Binaries

Seq: 400087 ObsId: 00720

Long-term Plan bin: 6-Mar-2000

ABSTRACT

We propose to survey the 7 remaining bright LMXBs (using HRC) and 1 quiescent NS-LMXB transient (using ACIS-I) in globular clusters for which accurate positions are not available. These will enable optical IDs with HST which then constrain the LMXB mass and evolution. Faint sources can be resolved with the HRC down to limits which will constrain the bright LMXB luminosity function. The deeper ACIS observation will measure the dim source content and qLMXB spectrum. The full 12 cluster LMXB data set can then constrain LMXB masses, the cluster potential, and dark remnant content of globular cluster cores.
