Title: THE LUMINOUS BURSTING X-RAY SOURCES IN GLOBULAR CLUSTER CORES: LOCATION, LOCATION, AND LOCATION

Observer: ANDERSON

ABSTRACT

The highly luminous bursting X-ray sources in the cores of globular clusters are some of the most exotic stellar systems known. Recently HST imaging has led to optical candidates for many of these central cluster sources, but these candidates have a diverse range of properties. Even for the most accurate (3") X-ray positions extant pre-AXAF, there are sometimes hundreds of candidate counterparts permitted on positional grounds alone; evidence is thus quite inconclusive, and some of the current candidates may be incorrect. We propose to obtain highly accurate AXAF positions for most of the known sources, reducing the number of candidates by up to 100X, using an instrument configuration that will also provide a homogeneous set of high resolution spectra for much of the sample.
