Abstract

Radio timing measurements of the binary millisecond pulsar J1614-2230 yielded high-precision mass measurements of the neutron star and white dwarf companion. The high orbital inclination angle, and large companion mass combined to produce a significant Shapiro Delay in the timing residuals, which betrayed the presence of the most massive neutron star currently known (M NS=1.97±0.04M). The primary implications of these findings are briefly summarized.
