Relativistic phenomena (orbital precession, Shapiro delay, and/or orbital decay) have been measured in Arecibo timing observations of four pulsar-white dwarf binaries, leading to constraints on the neutron star masses. We have detected the decay of the PSR J0751+1807 orbit due to gravitational radiation emission, the first such measurement in a binary with a low mass ratio (m_2/m_1<<1). Timing data constrains the mass of this pulsar to bet between 1.6 and 2.8 solar masses. Masses of the other… Expand

Equation of state constraints from neutron stars
Abstract Recent measurements of thermal radiation from neutron stars have suggested a rather broad range of radiation radii ( $R_{\infty}=R/\sqrt{1-2GM/Rc^{2}}\,$ ). Sources in M13 and Omega CenExpand

A test of general relativity from the three-dimensional orbital geometry of a binary pulsar
TLDR
High-precision radio observations of the binary millisecond pulsar PSR J0437-4715 are reported, which establish the three-dimensional structure of its orbit and see the Shapiro delay predicted by general relativity, and the mass of the neutron star and its white dwarf companion is determined.
