@article{Haensel2001AUE, title={A unified equation of state of dense matter and neutron star structure}, author={F. Haensel}, journal={Astronomy and Astrophysics}, year={2001}, volume={380}, pages={151-167} }

An equation of state (EOS) of neutron star matter, describing both the neutron star crust and the liquid core, is calculated. It is based on the eective nuclear interaction SLy of the Skyrme type, which is particularly suitable for the application to the calculation of the properties of very neutron rich matter (Chabanat et al. 1997, 1998). The structure of the crust, and its EOS, is calculated in the T = 0 approximation, and under the assumption of the ground state composition. The crust-core…
