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…

Equation-of-state-informed pulse profile modeling

Mariska Hoogkamer, Nathan Rutherford, Daniela Huppenkothen +9

NICER has enabled mass-radius inferences for pulsars using pulse profile modeling (PPM), providing constraints on the equation of state (EOS) of cold, dense matter. To date, PPM an…

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…

Parameter constraints for accreting millisecond pulsars with synthetic NICER data

Bas Dorsman, Tuomo Salmi, Anna L. Watts +10

Pulse profile modelling (PPM) is a technique for inferring mass, radius and hotspot properties of millisecond pulsars. PPM is now regularly used for analysis of rotation-powered mi…
