Hybrid stars that masquerade as neutron stars
We show that a hybrid (nuclear+quark matter) star can have a mass-radius relationship very similar to that predicted for a star made of purely nucleonic matter. We show this for a generic
Evolution of Proto-Neutron Stars
We study the thermal and chemical evolution during the Kelvin-Helmholtz phase of the birth of a neutron star, employing neutrino opacities that are consistently calculated with the underlying
Neutrino interactions in hot and dense matter
We study the charged and neutral current weak interaction rates relevant for the determination of neutrino opacities in dense matter found in supernovae and neutron stars. We establish an efficient
Medium modification of the charged-current neutrino opacity and its implications
Previous work on neutrino emission from proto-neutron stars which employed full solutions of the Boltzmann equation showed that the average energies of emitted electron neutrinos and antineutrinos
The maximum mass and radius of neutron stars and the nuclear symmetry energy
We calculate the equation of state of neutron matter with realistic two- and threenucleon interactions using Quantum Monte Carlo techniques, and demonstrate that the short-range three-neutron
Stringent constraints on neutron-star radii from multimessenger observations and nuclear theory
The properties of neutron stars are determined by the nature of the matter that they contain. These properties can be constrained by measurements of the star’s size. We obtain stringent constraints
Nucleon-nucleon bremsstrahlung of dark gauge bosons and revised supernova constraints
We calculate the rate of production of hypothetical light vector bosons (LVBs) from nucleon-nucleon bremsstrahlung reactions in hot and dense matter. We use the soft-radiation approximation and
Novel phases at high density and their roles in the structure and evolution of neutron stars
We present a pedagogic discussion on the role of novel phases of dense baryonic matter in ``neutron'' stars. Qualitative aspects of the physics that drives phase transitions and some of its
