PSR J0030+0451 Mass and Radius from NICER Data and Implications for the Properties of Neutron Star Matter
Bayesian modeling of NICER X-ray pulses from PSR J0030+0451 yields a neutron star radius near 13 km and mass of 1.44 solar masses, improving constraints on the equation of state above nuclear density.

Record completeness
Claims
We show that our measurements of Re and M for PSR J0030+0451 improve the astrophysical constraints on the equation of state of cold, catalyzed matter above nuclear saturation density.
The analysis assumes that the observed X-ray waveform is produced by a small number of uniform-temperature oval emitting regions whose geometry and temperature distribution can be adequately parameterized and that systematic uncertainties in the instrument response and atmosphere model are sub-dominant to the statistical errors.
Mass and radius of PSR J0030+0451 measured as 1.44 solar masses and 13.02 km, improving astrophysical constraints on the cold dense matter equation of state.
