Claims

C1strongest claim

the joint multi-instrument analysis yields a statistically viable and radio-consistent solution with a gravitational mass of 1.38±0.03 M⊙ and an equatorial circumferential radius of 13.25−0.35+0.34 km (68% confidence intervals). The hot-spot geometry consists of two spherical caps with uniform temperature distributions.

C2weakest assumption

The assumption that non-magnetized partially-ionized and fully-ionized hydrogen atmosphere models accurately describe the cold and hot thermal emission, combined with the informative prior on hot-spot geometry from radio polarization data.

C3one line summary

Joint multi-wavelength analysis of PSR J0437-4715 yields neutron star mass 1.38 solar masses and equatorial radius 13.25 km with two uniform-temperature hot spots at colatitudes of approximately 130 and 9 degrees.
