Accretion of cool stellar winds on Sgr A ∗ : another puzzle of the Galactic Centre ?

Abstract

Sgr A is currently being fed by winds from a cluster of gravitationally bound young mass-loosing stars. Using observational constraints on the orbits, mass loss rates and wind velocities of these stars, we numerically model the distribution of gas in the ∼ 0.1–10 region around Sgr A. We find that radiative cooling of recently discovered slow winds leads to… (More)
