A NICER view of the millisecond pulsar PSR J21243358: evidence for a helium atmosphere
Denis González-Caniulef, Sebastien Guillot, Pierre Stammler +12
Pulse profile modeling has proven to be a powerful technique for determining the mass and radius of neutron stars. To date, this method has been applied to a handful of millisecond…
Pulse profile modelling of the 2024 outburst of the accreting millisecond pulsar SRGA J144459.2-604207
Bas Dorsman, Tuomo Salmi, Anna L. Watts +14
Pulse profile modelling via relativistic ray-tracing can constrain the system parameters of neutron stars, notably their mass and radius. Among these objects, accreting millisecond…
Cross-Comparison of Sampling Algorithms for Pulse Profile Modeling of PSR J0740+6620
Mariska Hoogkamer, Yves Kini, Tuomo Salmi +2
In the last few years, NICER data has enabled mass and radius inferences for various pulsars, and thus shed light on the equation of state for dense nuclear matter. This is achieve…
A NICER View of PSR J0030+0451: Updated Constraints from Six Years of NICER Observations
Yves Kini, Lucien Mauviard, Tuomo Salmi +13
Pulse-profile modeling of rotation-powered millisecond pulsars targeted by NICER has enabled mass--radius constraints of several neutron star sources, with implications for the den…
A NICER view of the 1.4 solar-mass edge-on pulsar PSR J0614-3329
Lucien Mauviard, Sebastien Guillot, Tuomo Salmi +20
Four neutron star radius measurements have already been obtained by modeling the X-ray pulses of rotation-powered millisecond pulsars observed by the Neutron Star Interior Composit…
Dense Matter in Neutron Stars with eXTP
Ang Li, Anna L. Watts, Guobao Zhang +82
In this White Paper, we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission to constrain the equation of state of dense matter in neutron stars, explo…
