Astrophysical Measurement of the Equation of State of Neutron Star Matter

Published 2010-02-16, updated 2010-12-01Version 2

We present the first astrophysical measurement of the pressure of cold matter above nuclear saturation density, based on recently determined masses and radii of three neutron stars. The pressure at higher densities are below the predictions of equations of state that account only for nucleonic degrees of freedom, and thus present a challenge to the microscopic theory of neutron star matter.
