Though a significant number of these astrometric matches are likely to be spurious, we sought out spectral characteristics of active stars and interacting binaries, such as hot, massive spectral types or emission lines in or... ▽ More We have conducted a near - infrared spectroscopic survey of 47 candidate counterparts to X-ray sources discovered by the Chandra X-ray Observatory near the Galactic Center (GC).

Both basins are unexpectedly young, roughly 1 to 2 billion years, and their formation substantially reset Vestan geology and excavated enough diverse crust rocks to have created the Vestoids (asteroids with similar spectral characteristics that could be collisional fragments of Vesta) and the Howardite - Eucrite - Diogenite (HED) meteorites.
