A search for gravitational waves associated with the August 2006 timing glitch of the Vela pulsar
The LIGO Scientific Collaboration, J. Abadie, B. P. Abbott +499
The physical mechanisms responsible for pulsar timing glitches are thought to excite quasi-normal mode oscillations in their parent neutron star that couple to gravitational wave e…
Search for Gravitational Wave Bursts from Six Magnetars
J. Abadie, B. P. Abbott, R. Abbott +765
Soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are thought to be magnetars: neutron stars powered by extreme magnetic fields. These rare objects are characterized b…
Formation of the black-hole binary M33 X-7 via mass-exchange in a tight massive system
Francesca Valsecchi, Evert Glebbeek, Will M. Farr +5
M33 X-7 is among the most massive X-Ray binary stellar systems known, hosting a rapidly spinning 15.65 Msun black hole orbiting an underluminous 70 Msun Main Sequence companion in…
The intriguing evolutionary history of the massive black hole X-ray binary M33 X-7
Francesca Valsecchi, Evert Glebbeek, Will M. Farr +5
Black hole (BH) X-ray binaries (XRBs) are X-ray luminous binary systems comprising a BH accreting matter from a companion star. Understanding their origins sheds light on the still…
Field and Globular Cluster LMXBs in NGC 4278
G. Fabbiano, N. J. Brassington, L. Lentati +12
We report a detailed spectral analysis of the population of low-mass X-ray binaries (LMXBs) detected in the elliptical galaxy NGC~4278 with Chandra. Seven luminous sources were stu…
Analytical expressions for the envelope binding energy of giants as a function of basic stellar parameters
Andrew James Loveridge, Marc van der Sluys, Vassiliki Kalogera
The common-envelope (CE) phase is an important stage in the evolution of binary stellar populations. The most common way to compute the change in orbital period during a CE is to r…
