EVOLUTIONARY SEQUENCES FOR LOW- AND INTERMEDIATE-MASS X-RAY BINARIES
We present the results of a systematic study of the evolution of low- and intermediate-mass X-ray binaries (LMXBs and IMXBs). Using a standard Henyey-type stellar evolution code and a standard modelExpand

THE EFFECTS OF BINARY EVOLUTION ON THE DYNAMICS OF CORE COLLAPSE AND NEUTRON STAR KICKS
We systematically examine how the presence in a binary affects the final core structure of a massive star and its consequences for the subsequent supernova explosion. Interactions with a companionExpand

An Overabundance of Transient X-Ray Binaries within 1 Parsec of the Galactic Center
During 5 years of Chandra observations, we have identified seven X-ray transients located within 23 pc of Sgr A*. These sources each vary in luminosity by more than a factor of 10 and have peak X-rayExpand

A New Class of High-Mass X-Ray Binaries: Implications for Core Collapse and Neutron Star Recoil
We investigate an interesting new class of high-mass X-ray binaries (HMXBs) with long orbital periods (Porb > 30 days) and low eccentricities (e 0.2). The orbital parameters suggest that the neutronExpand

A Comprehensive Study of Neutron Star Retention in Globular Clusters
There is mounting evidence that as many as ~1000 neutron stars (NSs) may be present in some of the richest globular clusters in the Galaxy, which perhaps amounts to more than 10%-20% of the NSs everExpand

Probing the Spacetime around Sagittarius A* with Radio Pulsars
The supermassive black hole at the Galactic center harbors a bound cluster of massive stars that should leave neutron star remnants. Extrapolating from the available data, we estimate that ~1000Expand

Ellipsoidal Oscillations Induced by Substellar Companions: A Prospect for the Kepler Mission
Hundreds of substellar companions to solar-type stars will be discovered with the Kepler satellite. Kepler's extreme photometric precision gives access to low-amplitude stellar variabilityExpand

Bondi-Hoyle-Lyttleton Accretion Model for Low-Luminosity X-Ray Sources in Globular Clusters
We present a new model for low-luminosity X-ray sources in globular clusters, with LX 1034 ergs s-1. The model we propose is that of a single neutron star accreting from cluster gas that hasExpand

The Galactic Population of Low- and Intermediate-Mass X-Ray Binaries
We present the first study that combines binary population synthesis in the Galactic disk and detailed evolutionary calculations of low- and intermediate-mass X-ray binaries (L/IMXBs). Our approachExpand

The Orbit of X Persei and Its Neutron Star Companion
We have observed the Be/X-ray pulsar binary system X Per/4U 0352+30 on 61 occasions spanning an interval of 600 days with the PCA instrument on board the Rossi X-Ray Timing Explorer (RXTE). PulseExpand
