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…

New and updated timing models for seven young energetic X-ray pulsars, including the Big Glitcher PSR J0537-6910

Wynn C. G. Ho, Lucien Kuiper, Cristobal M. Espinoza +6

We present new timing models and update our previous ones for the rotational evolution of seven young energetic pulsars, including four of the top five in spin-down luminosity Edot…

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…
