A Robust Measure of Tidal Circularization in Coeval Binary Populations: The solar-type spectroscopic Binary Population in The Open Cluster M35
S. Meibom, R. D. Mathieu
We present a new homogeneous sample of 32 spectroscopic binary orbits in the young (~ 150 Myr) main-sequence open cluster M35. The distribution of orbital eccentricity vs. orbital…

The Tidal Circularization Cutoff Period of the Old Open Cluster NGC188
Robert D. Mathieu, Søren Meibom, Christopher J. Dolan
Based on a sample of 45 main-sequence solar-type spectroscopic binaries we find the tidal circularization cutoff in the open cluster NGC 188 (age 7 Gyr) to be well-defined at a per…
