Anisotropic Quark Stars with an Interacting Quark Equation of State
E. A. Becerra-Vergara, Sindy Mojica, F. D. Lora-Clavijo +1
A deep exploration of the parameter space that relates the interacting equation of state with the bag constant B, and the interaction parameter a, is fundamental for the constructi…
Innermost stable circular orbits of neutron stars in dilatonic-Einstein-Gauss-Bonnet theory
Guillermo A. Gonzalez, Burkhard Kleihaus, Jutta Kunz +1
The innermost stable circular orbits (ISCOs) around rapidly rotating neutron stars are studied in dilatonic Einstein-Gauss-Bonnet theory. Universal relations for properly scaled IS…
Quasinormal modes of compact objects in alternative theories of gravity
Jose Luis Blázquez-Salcedo, Zahra Altaha Motahar, Daniela D. Doneva +5
We address quasinormal modes of compact objects in several alternative theories of gravity. In particular, we focus on black holes and neutron stars with scalar hair. We consider b…
Black holes in Einstein-Gauß-Bonnet-dilaton theory
Jose Luis Blázquez-Salcedo, Vitor Cardoso, Valeria Ferrari +9
Generalizations of the Schwarzschild and Kerr black holes are discussed in an astrophysically viable generalized theory of gravity, which includes higher curvature corrections in t…
Rapidly Rotating Neutron Stars in Dilatonic Einstein-Gauss-Bonnet Theory
Burkhard Kleihaus, Jutta Kunz, Sindy Mojica +1
We construct sequences of rapidly rotating neutron stars in dilatonic Einstein-Gauss-Bonnet theory, employing two equations of state for the nuclear matter. We analyze the dependen…
Spinning black holes in Einstein--Gauss-Bonnet--dilaton theory: non-perturbative solutions
Burkhard Kleihaus, Jutta Kunz, Sindy Mojica +1
We present an investigation of spinning black holes in Einstein--Gauss-Bonnet--dilaton (EGBd) theory. The solutions are found within a non-perturbative approach, by directly solvin…
Axial quasi-normal modes of Einstein-Gauss-Bonnet-dilaton neutron stars
Jose Luis Blázquez-Salcedo, Luis Manuel González-Romero, Jutta Kunz +2
We investigate axial quasi-normal modes of realistic neutron stars in Einstein-Gauss-Bonnet-dilaton gravity. We consider 8 realistic equations of state containing nuclear, hyperoni…
Quadrupole Moments of Rapidly Rotating Compact Objects in Dilatonic Einstein-Gauss-Bonnet Theory
Burkhard Kleihaus, Jutta Kunz, Sindy Mojica
We consider rapidly rotating black holes and neutron stars in dilatonic Einstein-Gauss-Bonnet (EGBd) theory and determine their quadrupole moments, which receive a contribution fro…
Geometrothermodynamics of a Charged Black Hole of String Theory
Alexis Larranaga, Sindy Mojica
The thermodynamics of the Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) charged black hole from string theory is reformulated within the context of the recently developed for…
