Radial velocity study of four southern RS CVn candidates and related field stars.
DOI: 10.1086/112748 Bibcode: 1980AJ.....85..858S

Stencel, R. E.; Stacy, J. G.; Weiler, E. J.

Radial velocity variations are demonstrated for four southern RS CVn candidates: HD 39937, 101379, 155555, and 174429. The period of HD 155555 appears to have decreased by about one part in 100,000 over the past 18 yr. In addition, high-resolution observations of the Ca II H and K profiles and the Mg II 2800-A emission doublet are presented. These…
