Analysis of the Quiescent Low-Mass X-Ray Binary Population in Galactic Globular Clusters
Quiescent low-mass X-ray binaries (qLMXBs) containing neutron stars have been identified in several globular clusters using Chandra or XMM X-ray observations, via their distinctive soft thermalExpand
A Chandra X-Ray Study of the Dense Globular Cluster Terzan 5
We report a Chandra ACIS-I observation of the dense globular cluster Terzan 5. The previously known transient low-mass X-ray binary (LMXB) EXO 1745-248 in the cluster entered a rare high state duringExpand
A Chandra X-Ray Study of the Globular Cluster M80
We report our analysis of a Chandra X-ray observation of the rich globular cluster M80, in which we detect some 19 sources to a limiting 0.5-2.5 keV X-ray luminosity of 7*10^30 ergs/s within theExpand
X-Ray Studies of Two Neutron Stars in 47 Tucanae: Toward Constraints on the Equation of State
We report spectral and variability analysis of two quiescent low-mass X-ray binaries (X5 and X7, previously detected with the ROSAT HRI) in a Chandra ACIS-I observation of the globular cluster 47Expand
The high-energy polarization-limiting radius of neutron star magnetospheres - I. Slowly rotating neutron stars
In the presence of strong magnetic fields, the vacuum becomes a birefringent medium. We show that this quantum electrodynamics effect decouples the polarization modes of photons leaving the neutronExpand
The High-Energy Polarization-Limiting Radius of Neutron Star Magnetospheres II -- Magnetized Hydrogen Atmospheres
In the presence of strong magnetic fields, the vacuum becomes a birefringent medium. We show that this QED effect couples the direction of the polarization of photons leaving the NS surface, to theExpand

Model atmospheres and thermal spectra of magnetized neutron stars
Thermal surface radiation has been detected with X-ray instruments for several neutron stars with high spectral, spatial and timing resolution. These observations allow for direct study ofExpand
Toroidal fluid motion at the top of the Earth's core
SUMMARY Geomagnetic secular variation is caused by flow of liquid iron in the core. Geomagnetic observations can be used to determine properties of the flow but such calculations in general haveExpand
Properties of the isolated neutron star RX J185635-3754
Abstract Despite improved observational capabilities, the surface properties of neutron stars remain uncertain. In principle, multiwavelength spectra can reveal their compositions and angularExpand
