Long-term evolution of double white dwarf binaries accreting through direct impact
Kyle Kremer, Jeremy Sepinsky, Vassiliki Kalogera
We calculate the long-term evolution of angular momentum in double white dwarf binaries undergoing direct impact accretion over a broad range of parameter space. We allow the rotat…
Angular Momentum Changes Due to Direct Impact Accretion in a Simplified Binary System
Jeremy F. Sepinsky, Bart Willems, Vassiliki Kalogera +1
We model a circular mass-transferring binary system to calculate the exchange of angular momentum between stellar spins and the orbit due to direct impact of the mass transfer stre…
Interacting Binaries with Eccentric Orbits II. Secular Orbital Evolution Due To Non-Conservative Mass Transfer
J. F. Sepinsky, B. Willems, V. Kalogera +1
We investigate the secular evolution of the orbital semi-major axis and eccentricity due to mass transfer in eccentric binaries, allowing for both mass and angular momentum loss fr…
Interacting Binaries with Eccentric Orbits. Secular Orbital Evolution Due To Conservative Mass Transfer
J. F. Sepinsky, B. Willems, V. Kalogera +1
We investigate the secular evolution of the orbital semi-major axis and eccentricity due to mass transfer in eccentric binaries, assuming conservation of total system mass and orbi…
A Spectroscopic Analysis of Blue Stragglers, Horizontal Branch and Turn-Off Stars in Four Globular Clusters
Orsola De Marco, Michael M. Shara, D. Zurek +4
We present a spectroscopic analysis of HST/STIS and FOS low- and intermediate-resolution spectroscopy of 55 stars (turn-off stars, horizontal branch stars and blue stragglers) in f…
