Despite their long history and astrophysical importance, some of the key properties of
neutron stars are still uncertain. The extreme conditions encountered in their interiors …

In this article, I introduce ideas and techniques to extract information about the equation of
state of matter at very high densities from gravitational waves emitted before, during and …

We consider quarkyonic matter to naturally explain the observed properties of neutron stars.
We argue that such matter might exist at densities close to that of nuclear matter, and at the …

The theory of the nuclear energy-density functional is used to provide a unified and
thermodynamically consistent treatment of all regions of cold non-accreting neutron stars. In …

We study the mass-radius curve of hybrid stars, assuming a single first-order phase
transition between nuclear and quark matter, with a sharp interface between the quark …

If a phase transition is allowed to take place in the core of a compact star, a new stable
branch of equilibrium configurations can appear, providing solutions with the same mass as …

The composition of neutron stars at the extreme densities reached in their cores is currently
unknown. Besides nuclear matter of normal neutrons and protons, the cores of neutron stars …

We present a new Hartree-Fock-Bogoliubov nuclear mass model based on standard forms
of Skyrme and pairing functionals, which corresponds to the most accurate mass model we …

Neutron stars explore matter at the highest densities in the universe such that their inner
cores might undergo a phase transition from hadronic to exotic phases, eg, quark matter …

Extending our earlier work, a new family of three Hartree-Fock-Bogoliubov (HFB) mass
models, labeled HFB-30, HFB-31, and HFB-32, is presented, along with their underlying …
