Radial oscillations and tidal Love numbers of dark energy stars
Grigoris Panotopoulos, Angel Rincon, Ilidio Lopes
We investigate the properties of relativistic stars made of dark energy. We model stellar structure assuming i) isotropic perfect fluid and ii) a dark energy inspired equation of s…
Quark stars with isotropic matter in Hořava gravity and Einstein-æther theory
Grigoris Panotopoulos, Daniele Vernieri, Ilídio Lopes
We study non-rotating and isotropic strange quark stars in Lorentz-violating theories of gravity, and in particular in Hořava gravity and Einstein-æther theory. For quark matter we…
GW170817 constraints on the properties of a neutron star in the presence of WIMP dark matter
Abdul Quddus, Grigorios Panotopoulos, Bharat Kumar +2
The properties of a neutron star are studied in the presence of dark matter. We have considered a relatively light Weakly Interacting Massive Particle (WIMP) as a dark matter candi…
Scale-dependent (2+1) - dimensional electrically charged black holes in Einstein-power-Maxwell theory
Angel Rincon, Ernesto Contreras, Pedro Bargueño +2
In this work we extend and generalize our previous work on the scale dependence at the level of the effective action of black holes in the presence of non-linear electrodynamics. I…
Brane-bulk energy exchange : a model with the present universe as a global attractor
G. Kofinas, G. Panotopoulos, T. N. Tomaras
The role of brane-bulk energy exchange and of an induced gravity term on a single braneworld of negative tension and vanishing effective cosmological constant is studied. It is sho…
