I-Love-Q relations for Neutron Stars with Dark Energy
Simone D'Onofrio
The influence of a dark energy fluid on the equation of state of neutron stars is investigated. A detailed analysis is conducted for such models, including the computation of the m…

Generalized entropic dark energy with spatial curvature
Sergei D. Odintsov, Simone D'Onofrio, Tanmoy Paul
In the realm of thermodynamics of apparent horizon, we construct a dark energy (DE) model from 4-parameter generalized entropy of apparent horizon in a spatially non-flat universe.…

Primordial gravitational waves in horizon cosmology and constraints on entropic parameters
Sergei D. Odintsov, Simone D'Onofrio, Tanmoy Paul
The hallmark of the 4-parameter generalized entropy is that it can represent various known entropies proposed so far for suitable limits of the parameters, and thus the 4-parameter…
