  This volume contains most of the links to the presentations delivered at this
international workshop. This meeting was the second in the series following the
previous I Encuentro Ib\'erico de Compstar, held at the University of Coimbra,
Portugal in 2010. The main purpose of this meeting was to strengthen the
scientific collaboration between the participants of the Iberian and the rest
of the southern European branches of the European Nuclear Astrophysics network,
formerly, COMPSTAR. This ESF (European Science Foundation) supported network
has been crucial in helping to make a broader audience for the the most
interesting and relevant research lines being developed currently in Nuclear
Astrophysics, especially related to the physics of neutron stars. The program
of the meeting was tailored to theoretical descriptions of the physics of
neutron stars although some input from experimental observers and other
condensed matter and optics areas of interest was also included.
