What Velocities and Eccentricities tell us about Radial Migration
Ralph Schoenrich
This note attempts to interpret some of the recent findings about a downtrend in the mean azimuthal velocity of low [alpha/Fe] thin disc stars with increasing metallicity. The pres…
The detection and treatment of distance errors in kinematic analyses of stars
Ralph Schoenrich, James Binney, Martin Asplund
We present a new method for detecting and correcting systematic errors in the distances to stars when both proper motions and line-of-sight velocities are available. The method, wh…
A new formula for disc kinematics
Ralph Schoenrich, James Binney
In a disc galaxy the distribution of azimuthal components of velocity is very skew. In the past this skewness has been modelled by superposed Gaussians. We use dynamical arguments…
New constraints on the chemical evolution of the solar neighbourhood and Galactic disc(s). Improved astrophysical parameters for the Geneva-Copenhagen Survey
Luca Casagrande, Ralph Schoenrich, Martin Asplund +5
We present a re-analysis of the Geneva-Copenhagen survey, which benefits from the infrared flux method to improve the accuracy of the derived stellar effective temperatures and use…
