THE NUCLEAR CLUSTER OF THE MILKY-WAY - STAR-FORMATION AND VELOCITY DISPERSION IN THE CENTRAL 0.5 PARSEC
- Abstract:
-
We report the first results of an extensive new study of the Galactic center stellar cluster. The central parsec is powered by a cluster of about two dozen luminous and helium-rich blue supergiants/Wolf-Rayet stars (Teff ∼ 20,000-30,000 K) with ZAMS masses up to ∼100 M⊙. The most likely scenario for the formation of the massive stars is a small star formation burst between 3 × 106 and 7 × 106 years ago. In this scenario the Galactic center is presently in a short-lived, post-main-sequence "wi...
