Nearest millisecond pulsar has radius of 11.4 kilometers and is 1.4x as heavy as the sun, researchers find

The nearest millisecond pulsar PSR J0437-4715 has a radius of 11.4 kilometers and a mass 1.4 times that of the sun. These are the results of precision measurements made by a team of researchers led by the University of Amsterdam (the Netherlands). The measurements reveal more about the composition and magnetic field of this neutron star. The researchers are publishing their findings in a series of scientific papers.
