A Not-So-Compact Companion: Massive, Oversize White Dwarf in a Post-Common Envelope Eclipsing Binary
Erin M. Motherway, Evan Linck, Robert D. Mathieu +5
We provide a detailed characterization of 2M07515777+1807352, a post-common envelope eclipsing binary system with a 10.3 d, nearly, but not quite, circular orbit (e = 0.02). This s…

WIYN Open Cluster Study. XCVII. An Extended Radial-Velocity Survey and Spectroscopic Binary Orbits in the Open Cluster NGC 188
Ritvik Sai Narayan, Evan Linck, Robert D. Mathieu +1
We present 35 new spectroscopic-binary orbits from our extended radial-velocity (RV) survey of the old ( Gyr) open cluster NGC 188. Using data from the WIYN Open Clust…

Calibration of Binary Population Synthesis Models Using White Dwarf Binaries from APOGEE, GALEX and Gaia
A. C. Rubio, K. Breivik, C. Badenes +5
The effectiveness and stability of mass transfer in binaries system are crucial in determining its final product. Rapid binary population synthesis (BPS) codes simplify the complex…
