SUMMARY OF SEQUENCE NUMBER 300003
Title: DIFFUSE X-RAY EMISSION IN GLOBULARS: HOT GAS VS. NON-THERMAL EMISSION IN 47 TUC
Observer: MURRAY
Subject Category: WD Binaries and CVs
Seq: 300003 ObsId: 00078
Long-term Plan bin: 15-Mar-2000
ABSTRACT
We propose a deep ACIS-S observation of 47 Tuc to confirm and map our ROSAT discovery of diffuse emission from a probable bow shock and possible non-thermal emission from the large population of millisecond pulsars. The bow shock emission will be mapped out to 5-10arcmin from the peak diffuse emission and measure the proper motion of the cluster in the Galaxy. The spectral distribution will constrain both the mass loss of cluster stars and the temperature-density of the hot gas in the galactic halo. The possible IC emission from low energy CR electrons accelerated in the bow shock will constrain the MSP population and particle production in the cluster, while the spectra of point sources will complement and extend our deep HRC-I survey for CVs and dim x-ray sources in this key cluster.
