Extended Data Fig. 4: The period and luminosity distribution of pulsars with measured mass.
From: Determination of the birth-mass function of neutron stars from observations
a, Measured mass versus spin period for 39 recycled pulsars (blue) in group A (‘Modelling the accreted masses of recycled pulsars’ in Methods) and the remaining neutron stars (orange). b, Measured mass versus luminosity at 1.4 GHz for 39 recycled pulsars, where the horizontal error bars account for uncertainties in the flux density and distance. We adopted the distance estimates from the Australia Telescope National Facility Pulsar Catalogue while assuming a 20% error. In both panels, plotted are mean values with 1σ credible errors, while the measurement uncertainty of spin periods in the upper panel is too small to be seen.
