摘要：

We apply the statistical measure of complexity introduced by Lopez-Ruiz, Mancini and Calbet (1995) [1] to neutron star structure. We continue the recent application of Sanudo and Pacheco (2009) [2] to white dwarfs. The interplay of gravity, the short-range nuclear force and the very short-range weak interaction shows that neutron stars, under the current theoretical framework, are ordered (low complexity) systems.
