Thermonuclear (Type I) X-Ray Bursts Observed by the Rossi X-Ray Timing Explorer
We have assembled a sample of 1187 thermonuclear (type I) X-ray bursts from observations of 48 accreting neutron stars by the Rossi X-ray Timing Explorer, spanning more than 10 years. The sample…
Neutron Star Mass Measurements. I. Radio Pulsars
There are now about 50 known radio pulsars in binary systems, including at least five in double neutron star binaries. In some cases, the stellar masses can be directly determined from measurements…
Observations of Accreting Pulsars
We discuss recent observations of accreting binary pulsars with the all-sky BATSE instrument on the Compton Gamma Ray Observatory. BATSE has detected and studied nearly half of the known accreting…
An ultraluminous X-ray source powered by an accreting neutron star
The majority of ultraluminous X-ray sources are point sources that are spatially offset from the nuclei of nearby galaxies and whose X-ray luminosities exceed the theoretical maximum for spherical…
The two-hour orbit of a binary millisecond X-ray pulsar
Typical radio pulsars are magnetized neutron stars that are born rapidly rotating and slow down as they age on time scales of 10 to 100 million years. In contrast, millisecond radio pulsars spin very…
A NICER View of PSR J0030+0451: Millisecond Pulsar Parameter Estimation
We report on Bayesian parameter estimation of the mass and equatorial radius of the millisecond pulsar PSR J0030+0451, conditional on pulse-profile modeling of Neutron Star Interior Composition…
A debris disk around an isolated young neutron star
TLDR
The discovery of mid-infrared emission from a cool disk around an isolated young X-ray pulsar, which resembles protoplanetary disks seen around ordinary young stars, suggesting the possibility of planet formation around young neutron stars.
Discovery of a High-Latitude Accreting Millisecond Pulsar in an Ultracompact Binary
We have identified the third known accretion-powered millisecond pulsar, XTE J0929-314, with the Rossi X-Ray Timing Explorer. The source is a faint, high Galactic latitude X-ray transient (d 5 kpc)…
The Disk-Magnetosphere Interaction in the Accretion-powered Millisecond Pulsar SAX J1808.4–3658
The recent discovery of the first known accretion-powered millisecond pulsar with the Rossi X-Ray Timing Explorer provides the first direct probe of the interaction of an accretion disk with the…
Rapid Spin-Up Episodes in the Wind-fed Accreting Pulsar GX 301–2
The accreting pulsar GX 301-2 (P = 680 s) has been observed continuously by the large-area detectors of the Burst and Transient Source Experiment (BATSE) instrument on the Compton Gamma Ray…
