Methods of the Long-term Radial-Velocity Variation Removal and their Application to Detect Duplicity of Several Be Stars
Published online by Cambridge University Press: 23 April 2012
Abstract
There are several types of binary stars which show non-periodical radial velocity variations with the amplitude larger than those connected with the orbital motion. The non-periodical changes have to be removed in order to study the orbital ones. We propose three removal techniques, two of which are based on the trend modeling with continuous functions and the third one that takes the orbital motion into account.
