An accurate metric for the spacetime around neutron stars
George Pappas
The problem of having an accurate description of the spacetime around neutron stars is of great astrophysical interest. For astrophysical applications, one needs to have a metric t…
Generalized continuity equations from two-field Schrödinger Lagrangians
Aris G. B. Spourdalakis, George Pappas, Christian V. Morfonios +3
A variational scheme for the derivation of generalized, symmetry-induced continuity equations for Hermitian and non-Hermitian quantum mechanical systems is developed. We introduce…
Astrophysical applications of the post-Tolman-Oppenheimer-Volkoff formalism
Kostas Glampedakis, George Pappas, Hector O. Silva +1
The bulk properties of spherically symmetric stars in general relativity can be obtained by integrating the Tolman-Oppenheimer-Volkoff (TOV) equations. In previous work we develope…
