The Role of the Equation of State in Binary Mergers
Sasa Ratkovic, Madappa Prakash, James M. Lattimer
Binary mergers involving black holes and neutron stars have been proposed as major sources of gravitational waves, r--process nucleosynthesis, and gamma ray bursters. In addition,…
Roche Lobes in the Second Post-Newtonian Approximation
Sasa Ratkovic, Madappa Prakash, James M. Lattimer
Close binary systems of compact stars, due to the emission of gravitational radiation, may evolve into a phase in which the less massive star transfers mass to its companion. We de…
Mergers of binary stars: The ultimate heavy-ion experience
Madappa Prakash, Sasa Ratkovic, James M. Lattimer
The mergers of black hole-neutron star binaries are calcuated using a pseudo-general relativistic potential that incorporates post-Newtonian corrections.…
Neutrino Processes in Supernovae and Neutrons Stars in Their Infancy and Old Age
M. Prakash, S. Ratkovic, S. I. Dutta +1
Neutrino processes in semi-transparent supernova matter, opaque to semi-transparent protoneutron star matter, and catalyzed neutron stars are discussed.
The photo-neutrino process in astrophysical systems
Sharada Iyer Dutta, Sasa Ratkovic, Madappa Prakash
Explicit expressions for the differential and total rates and emissivities of neutrino pairs from the photo-neutrino process in hot and dense matter…
Differential Neutrino Rates and Emissivities from the Plasma Process in Astrophysical Systems
Sasa Ratkovic, Sharada Iyer Dutta, Madappa Prakash
The differential rates and emissivities of neutrino pairs from an equilibrium plasma are calculated for the wide range of density and temperature encountered in astrophysical syste…
