A Search For Cepheid Binaries Using the Call H And K Lines
Published online by Cambridge University Press: 12 April 2016
Abstract
A survey of 24 classical Cepheids has been made to search for blue companions using the Call H and K lines. It is shown that this technique can detect an early A companion for a typical Cepheid. A blue companion of SU Cas was discovered and upper limits for the companions for a number of previously suspected binaries were established.
