Common Envelope Mergers: A Possible Channel for Forming Single sdB Stars
Michael Politano, Ronald E. Taam, Marc van der Sluys +1
We quantify an evolutionary channel for single sdB stars based on mergers of binaries containing a red giant star and a lower mass main sequence or brown dwarf companion in our Gal…
Population Synthesis Studies of Close Binary Systems Using a Variable Common Envelope Efficiency Parameter: I. Dependence upon Secondary Mass
Michael Politano, Kevin P. Weiler
We perform population synthesis calculations of present-day post common envelope binaries (PCEBs) and zero-age cataclysmic variables (ZACVs) using a common envelope efficiency para…
The Distribution of Secondary Masses in Post-Common Envelope Binaries: A Potential Test of Disrupted Magnetic Braking
Michael Politano, Kevin P. Weiler
The distribution of secondary star masses in present-day post-common envelope binaries (PCEBs) is calculated using four different models for angular momentum loss (AML) during the…
The Formation of Cataclysmic Variables with Brown Dwarf Secondaries
Michael Politano
The present-day formation of cataclysmic variables (CVs) with brown dwarf (BD) secondaries (0.013 M_sun < M_sec < 0.075 M_sun) is investigated using a population synthesis techniqu…
