Neutron Star Observations: Prognosis for Equation of State Constraints
James M. Lattimer, Maddapa Prakash
We investigate how current and proposed observations of neutron stars can lead to an understanding of the state of their interiors and the key unknowns: the typical neutron star ra…
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…
Constraining the Equation of State with Moment of Inertia Measurements
James M. Lattimer, Bernard F. Schutz
We estimate that the moment of inertia of star A in the recently discovered double pulsar system PSR J0737-3039 may be determined after a few years of observation to something like…
The Ultimate Energy Density of Observable Cold Matter
James M. Lattimer Madappa Prakash
We demonstrate that the largest measured mass of a neutron star establishes an upper bound to the energy density of observable cold matter. An equation of state-independent express…
The Physics of Neutron Stars
J. M. Lattimer, M. Prakash
Neutron stars are some of the densest manifestations of massive objects in the universe. They are ideal astrophysical laboratories for testing theories of dense matter physics and…
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.…
