The Local Galactic Escape Velocity1
Published online by Cambridge University Press: 04 August 2017
Abstract
From a new photometric and spectroscopic survey of high proper motion stars, combined with previously published work, we find that the local value of the escape velocity from the Galaxy exceeds 500 km s−1. This gives direct dynamical evidence that the total Galactic mass exceeds the mass inside the solar orbit by a factor of at least five.
