The mass of the PSR 2303 + 46 system
Description
As the result of timing observations over the last year using the 76-m Lovell Telescope at Jodrell Bank, we have determined the rate of periastron advance of the binary pulsar PSR 2303+46 to be ω =00.0108±00.0008 yr-1. If the advance of periastron is solely due to relativistic effects, then the total mass of the system is 2.9±0.3 solar masses, consistent with a pair of neutron stars both close to the Chandrasekhar mass of 1.4 solar masses. The mass of the PSR 2303+46 system is remarkably close to that of the PSR 1913+16 system, which contains the only other two neutron stars with accurately determined masses. (author)
