The Sagittarius dwarf mass-to-light ratio
Published online by Cambridge University Press: 08 November 2005
Abstract
We report on the use of high-resolution spectra to obtain a detailed description of the Sagittarius dwarf spheroidal internal dynamics, its Mass and Mass to Light ratio (M/L). Our direct measure of the central velocity dispersion of SGR give $\sigma_{SGR}=8.1\pm0.4$ km/s which translates in a total mass estimate of $M_{SGR} =1.6\times10^8 M_{\odot}$ and corresponding $(M/L)_{SGR}=9.1 (M/L)_{\odot}$. We also report on a possible detection of rotation in the core of SGR.
