The Blue Straggler F190: A Case for Mass Transfer
Published online by Cambridge University Press: 07 August 2017
Abstract
The blue straggler F190 is a member of the old open cluster M67. We argue that F190 may still be in the final stages of the mass transfer that has made it into a blue straggler. We use the turnoff mass of the cluster and the mass function derived from the spectroscopic orbit for F190 to constrain the masses of each member of the binary, both before mass transfer and now. We find that the mass transfer must have been nearly 100 percent efficient.
