The Centre-of-Mass Velocity of a Radially Pulsating Star: Insights from NLTE Models
Published online by Cambridge University Press: 12 April 2016
Abstract
The problem of deriving the centre-of-mass velocity of a radially pulsating star is reexamined. New observations of line asymmetry and Non-LTE radiation hydrodynamics point to a systematic effect of about 1 km s−1 in Cepheids.
