Steps Towards Absolute Accuracy In Radial Velocities1
Published online by Cambridge University Press: 12 April 2016
Abstract
We are developing methods to reach high absolute accuracy in spectroscopic radial velocities for stars of different spectral types. The basic idea is to remove the effects from convection and surface gravity that cause large systematic errors, in order to improve the absolute accuracy of radial velocities by one order of magnitude. This paper briefly describes observations and methodology in computing the radial velocities.
