PRECISION TIMING OF PSR J0437-4715: AN ACCURATE PULSAR DISTANCE, A HIGH PULSAR MASS, AND A LIMIT ON THE VARIATION OF NEWTON'S GRAVITATIONAL CONSTANT

摘要

Analysis of 10 years of high-precision timing data on the millisecond pulsar PSR J0437-4715 has resulted in a model-independent kinematic distance based on an apparent orbital period derivative, P_b, determined at the 1.5% level of precision (D_k = 157.0
