Pulse profiles of accreting neutron stars - A review of analysis methods, observations, and theoretical models
Katja Pottschmidt, Peter Kretschmar, Ekaterina Sokolova-Lapa +25
X-ray pulsars are highly magnetized ( G) neutron stars accreting from a donor star. Their characteristic X-ray emission arises from accreted material decelerated fro…
The Radius of PSR J0437-4715 from NICER Data
M. C. Miller, A. J. Dittmann, I. M. Holt +12
Neutron star Interior Composition Explorer (NICER) data have been used to estimate the masses and radii of the rotation-powered millisecond pulsars PSR J00300451, PSR J074066…
A NICER View of PSR J12311411: A Complex Case
Tuomo Salmi, Julia S. Deneva, Paul S. Ray +16
Recent constraints on neutron star mass and radius have advanced our understanding of the equation of state (EOS) of cold dense matter. Some of them have been obtained by modeling…
Exploring Waveform Variations among Neutron Star Ray-tracing Codes for Complex Emission Geometries
Devarshi Choudhury, Anna L. Watts, Alexander J. Dittmann +8
Pulse Profile Modeling (PPM), the technique used to infer mass, radius and geometric parameters for rotation-powered millisecond pulsars using data from the Neutron Star Interior C…
The Radius of the High-mass Pulsar PSR J0740+6620 with 3.6 yr of NICER Data
Tuomo Salmi, Devarshi Choudhury, Yves Kini +14
We report an updated analysis of the radius, mass, and heated surface regions of the massive pulsar PSR J0740+6620 using Neutron Star Interior Composition Explorer (NICER) data fro…
Sharp Periodic Flares and Long-Term Variability in the High-Mass X-ray Binary XTE J1829-098 from RXTE PCA, Swift BAT and MAXI Observations
Robin H. D. Corbet, Ralf Ballhausen, Peter A. Becker +20
XTE J1829-098 is a transient X-ray pulsar with a period of ~7.8 s. It is a candidate Be star system, although the evidence for this is not yet definitive. We investigated the twent…
