Title: Absorption and Abundances in the Ultracompact Binary 4U 0614+091

PI Name: Claude Canizares

We propose to study compositions and structures of inter- and circumstellar matter using HETGS observations of the X-ray binary 4U 0614+091. We will test the TBNEW absorption model developed for XSPEC from our absorption studies for O K, Fe L, and Ne K, compare abundances for O II/III and Ne II/III with the other sample, obtain Ne/O abundance ratio and compare with other binaries, specifically ultra-compacts, measure EWs in line absorption from Ne IX, O VIII, O VII ions to characterize the hot ISM gas toward the anti-GC region

Title: ChIcAGO: Chandra Identification of ASCA Galactic Objects

PI Name: Bryan Gaensler

X-ray sources in the Galactic plane trace a variety of exotic populations. Most sources with X-ray fluxes above 1e-11 erg/cm^2/s are well-known objects, while below 1e-13 erg/cm^2/s, AGN, CVs, and active stars dominate. However, many low-latitude sources lie between these two regimes, corresponding to young populations of pulsars, magnetars, hot stars and supernova remnants. To derive the birth-rates, lifetimes and distributions of these relatively rare sources, we propose to localize the unidentified objects in the 60% of the Galactic disk covered by the ASCA Galactic Plane Survey. Combined with archival analyses, multi-wavelength follow-up and the results of previous surveys, this will complete the demography of Galactic X-ray sources, from Sco X-1 down to the faintest sources known.
