New Galactic High Mass X-ray Binaries discovered with INTEGRAL
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
I will review the main observational properties of the new Galactic High Mass X-ray Binaries discovered by the INTEGRAL satellite in the hard energy range 17-100 keV.
Non-radial pulsations in the Be/X binaries 4U0115+63 and SAXJ2103.5+4545
Solar and Stellar Astrophysics (astro-ph.SR) High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
The discovery of non-radial pulsations (NRP) in the Be/X binaries of the Magellanic Clouds (MC, eg. Fabrycky 2005, Coe et al. 2005, Schmidtke & Cowley 2005) provided a new approach to understand these...
Resolved Spectroscopy of M Dwarf/L Dwarf Binaries. IV. Discovery of an M9 + L6 BInary Separated by Over 100 AU
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/27
We report the discovery of a faint L6 \pm 1 companion to the previously known M9 dwarf, 2MASS J01303563-4445411, based on our near-infrared imaging and spectroscopic observations with the 3m Infrared ...
The distribution of eccentricity of compact binaries
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
The current gravitational wave detectors have reached their operational sensitivity and are nearing detection of compact object binaries. In the coming years we expect that the Advanced LIGO/VIRGO wil...
Intermediate Mass Ratio Black Hole Binaries: Numerical Relativity meets Perturbation Theory
black-hole binaries proof-of-concept
2010/3/17
We study black-hole binaries in the intermediate-mass-ratio regime 0.01 < q < 0.1 with a new technique that makes use of nonlinear numerical trajectories and efficient perturbative evolutions to compu...
The search for spinning black hole binaries in mock LISA data using a genetic algorithm
black hole binaries genetic algorithm
2010/3/18
Coalescing massive Black Hole binaries are the strongest and probably the most important gravitational wave sources in the LISA band. The spin and orbital precessions bring complexity in the waveform ...
Advances in Simulations of Generic Black-Hole Binaries
Black-Hole Binaries hybrid post-Newtonian
2010/3/18
We review some of the recent dramatic developments in the fully nonlinear simulation of generic, highly-precessing, black-hole binaries, and introduce a new approach for generating hybrid post-Newtoni...
Accurate evolutions of unequal-mass neutron-star binaries: properties of the torus and short GRB engines
neutron-star binaries unequal-mass short GRB engines
2010/3/18
We present new results from accurate and fully general-relativistic simulations of the coalescence of unmagnetized binary neutron stars with various mass ratios. The evolution of the stars is followed...
Persistent junk solutions in time-domain modeling of extreme mass ratio binaries
extreme mass ratio binar time-domain modeling
2010/3/17
In the context of metric perturbation theory for non-spinning black holes, extreme mass ratio binary (EMRB) systems are described by distributionally forced master wave equations. Numerical solution o...

Radial velocities—spectroscopicbinaries—orbits—stars
2010/9/15
About 25 years ago, in Paper 12 of this series, the author presented a spectroscopic orbit for 6 Boo. The velocity amplitude of little more than 1 km s−1 was much smaller than for any star whose...

THEORETICAL STUDY OF IRRADIATION EFFECTS IN CLOSE BINARIES
Radiative transfer binaries: close
2010/10/29
The effect of irradiation is studied in a close binary system as-suming that the secondary component is a point source, moving in a circular orbit.The irradiation e®ects are calculated on the atmo...
