Abstract

Pulsar Tests Gravity Because of their extremely high densities, massive neutron stars can be used to test gravity. Based on spectroscopy of its white dwarf companion, Antoniadis et al. (p. 448 ) identified a millisecond pulsar as a neutron star twice as heavy as the Sun. The observed binary's orbita...
