EVOLUTIONARY SEQUENCES FOR LOW- AND INTERMEDIATE-MASS X-RAY BINARIES
- P. Podsiadlowski, S. Rappaport, Eric D. Pfahl
- Physics
- 15 July 2001
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 model… Expand
THE EFFECTS OF BINARY EVOLUTION ON THE DYNAMICS OF CORE COLLAPSE AND NEUTRON STAR KICKS
- P. Podsiadlowski, N. Langer, A. J. Poelarends, S. Rappaport, A. Heger, Eric D. Pfahl
- Physics
- 22 September 2003
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 companion… Expand
An Overabundance of Transient X-Ray Binaries within 1 Parsec of the Galactic Center
- M. Muno, Eric D. Pfahl, +7 authors Penn State
- Physics
- 17 December 2004
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-ray… Expand
A New Class of High-Mass X-Ray Binaries: Implications for Core Collapse and Neutron Star Recoil
- Eric D. Pfahl, S. Rappaport, P. Podsiadlowski, H. Spruit
- Physics
- 27 September 2001
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 neutron… Expand
A Comprehensive Study of Neutron Star Retention in Globular Clusters
- Eric D. Pfahl, S. Rappaport, P. Podsiadlowski
- Physics
- 7 June 2001
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 ever… Expand
Probing the Spacetime around Sagittarius A* with Radio Pulsars
- Eric D. Pfahl, A. Loeb
- Physics
- 27 September 2003
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 ~1000… Expand
Ellipsoidal Oscillations Induced by Substellar Companions: A Prospect for the Kepler Mission
- Eric D. Pfahl, P. Arras, B. Paxton
- Physics
- 15 April 2007
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 variability… Expand
Bondi-Hoyle-Lyttleton Accretion Model for Low-Luminosity X-Ray Sources in Globular Clusters
- Eric D. Pfahl, S. Rappaport
- Physics
- 13 September 2000
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 has… Expand
The Galactic Population of Low- and Intermediate-Mass X-Ray Binaries
- Eric D. Pfahl, S. Rappaport, P. Podsiadlowski
- Physics
- 13 March 2003
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 approach… Expand
The Orbit of X Persei and Its Neutron Star Companion
- H. Delgado-Marti, A. Levine, Eric D. Pfahl, S. Rappaport
- Physics
- 18 April 2000
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). Pulse… Expand
