Double Compact Objects I: The Significance Of The Common Envelope On Merger Rates
Double Compact Objects Significance Common Envelope Merger Rates
2012/2/23
The development of gravitational wave observatories (Advanced LIGO/Virgo, Einstein Telescope) is proceeding apace, and the direct detection of gravitational waves should be imminent. The last decade o...
Simulating the Common Envelope Phase of a Red Giant Using SPH and Uniform Grid Codes
Simulating Common Envelope Phase Red Giant Using SPH Uniform Grid Codes
2011/10/21
We use three-dimensional hydrodynamical simulations to study the rapid infall phase of the common envelope interaction of a red giant branch star of mass equal to 0.88 \msun and a companion star of ma...
An AMR Study of the Common Envelope Phase of Binary Evolution
AMR Study Common Envelope Phase Binary Evolution
2011/10/12
The hydrodynamic evolution of the common envelope phase of a low mass binary composed of a 1.05 Msun red giant and a 0.6 Msun companion has been followed for five orbits of the system using a high res...
Accretion in the detached post-common-envelope binary LTT 560
binaries: close – Stars: late-type – white dwarfs – Stars: individual: LTT 560 – cataclysmic variables
2011/10/11
In a previous study, we found that the detached post-common-envelope binary LTT 560 displays an Halpha emission line consisting of two anti-phased components. While one of them was clearly caused by s...
On the alpha formalism for the common envelope interaction
the alpha formalism the common envelope interaction
2011/1/10
The {\alpha}-formalism is a common way to parametrize the common envelope interaction between a giant star and a more compact companion. The {\alpha} parameter describes the fraction of orbital energy...
Two planets orbiting the recently formed post-common envelope binary NN Serpentis
Solar and Stellar Astrophysics (astro-ph.SR) Earth and Planetary Astrophysics (astro-ph.EP)
2011/1/7
Planets orbiting post-common envelope binaries provide fundamental information on planet formation and evolution. We searched for such planets in NN Ser ab, an eclipsing short-period binary that shows...
Masses and envelope binding energies of primary stars at the onset of a common envelope
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
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 et al. (2010) and f...
