The final orbital separation in common envelope evolution
Michael Politano
In the majority of population synthesis calculations of close binary stars, the common envelope (CE) phase is modeled using a standard prescription based upon the conservation of e…
Masses and envelope binding energies of primary stars at the onset of a common envelope
Marc van der Sluys, Michael Politano, Ronald E. Taam
We present basic properties of primary stars that initiate a common envelope (CE) in a binary, while on the giant branch. We use the population-synthesis code described in Politano…
Population Synthesis of Common Envelope Mergers: I. Giant Stars with Stellar or Substellar Companions
Michael Politano, Marc van der Sluys, Ronald E. Taam +1
Using a population synthesis technique, we have calculated detailed models of the present-day field population of objects that have resulted from the merger of a giant primary and…
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…
