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…
Multipole moments in scalar-tensor theory of gravity
George Pappas, Thomas P. Sotiriou
Stationary, asymptotically flat spacetimes in general relativity can be characterized by their multipole moments. The moments have proved to be very useful tools for extracting inf…
Why I-Love-Q
Kent Yagi, Leo C. Stein, George Pappas +2
Black holes are said to have no hair because all of their multipole moments can be expressed in terms of just their mass, charge and spin angular momentum. The recent discovery of…
