J/ApJ/521/682  Binaries in the Praesepe and Coma clusters   (Abt+, 1999)

Binaries in the Praesepe and Coma star clusters and their implications for binary evolution Abt H.A., Willmarth D.W. <Astrophys. J. 521, 682 (1999)> =1999ApJ...521..682A
ADC_Keywords: Binaries, spectroscopic ; Clusters, open ; Spectroscopy Keywords: binaries: spectroscopic - open clusters and associations: individual (Coma, Praesepe) - stars: evolution - stars: statistics Abstract: This completes a study of the evolution of binary systems in five open clusters of various ages. Among 21 stars observed in Praesepe, eight are found or confirmed to be spectroscopic binaries and orbital elements are derived, while one more shows long-term binary motion. Among 18 stars observed in the Coma Berenices cluster, five are found or confirmed to be spectroscopic binaries and orbital elements are derived, while a sixth has tentative elements. File Summary:
