Comparison of statistical treatments for the equation of state for core-collapse supernovae
S. R. Souza, A. W. Steiner, W. G. Lynch +2
Neutrinos emitted during the collapse, bounce and subsequent explosion provide information about supernova dynamics. The neutrino spectra are determined by weak interactions with n…
Quark Matter in Neutron Stars: An apercu
Prashanth Jaikumar, Sanjay Reddy, Andrew W. Steiner
The existence of deconfined quark matter in the superdense interior of neutron stars is a key question that has drawn considerable attention over the past few decades. Quark matter…
Minimal Cooling of Neutron Stars: A New Paradigm
Dany Page, James M. Lattimer, Madappa Prakash +1
A new classification of neutron star cooling scenarios, involving either ``minimal'' cooling or ``enhanced'' cooling is proposed. The minimal cooling scenario replaces and extends…
Observability of Neutron Stars with Quarks
Madappa Prakash, James M. Lattimer, Andrew W. Steiner +1
Recent Chandra observations have raised expectations that the objects RX J185635-3754 and 3C58 are either bare strange quark stars or stars with extended quark cores. However, thes…
Evolution of Proto-Neutron Stars with Quarks
Jose A. Pons, Andrew W. Steiner, Madappa Prakash +1
Neutrino fluxes from proto-neutron stars with and without quarks are studied. Observable differences become apparent after 10--20 s of evolution. Sufficiently massive stars contain…
Diffusion of Neutrinos in Proto-Neutron Star Matter with Quarks
Andrew W. Steiner, Madappa Prakash, James M. Lattimer
Neutrino opacities important in the evolution of a proto-neutron star containing quark matter are studied. The results for pure quark matter are compared with limiting expressions…
