Abstract We propose to analyze NICMOS observations of the central 5 pc of the Milky Way Galaxy in order to identify the nature of X-ray sources recently detected in a deep set of Chandra observations. We plan to determine the relative numbers of high-mass X-ray binaries with characteristic ages of 10^7 years, and magnetically accreting cataclysmic variables with ages of over 10^9 years. The results will provide information about the recent star formation history, the propensity for binaries to form, and the mass of stellar remnants at the Galactic center. ------------------------------------------------------------------------------------ 10285( 1) - 04/02/04 10:48 - [ 2] Summary Form for Proposal 10285 Item Used in this proposal ------------------------------------------------------------------------------------------------------------------------------------ Proposal Category AR ------------------------------------------------------------------------------------------------------------------------------------
