White dwarfs are a class of stars with unique physical properties. They present many
challenging problems whose solution requires advanced theories of dense matter, state-of …

In this work, we propose the modeling of static wormholes within the f (R, T) extended theory
of gravity perspective. We present some models of wormholes, which are constructed from …

In this work we investigate the equilibrium configurations of white dwarfs in a modified
gravity theory, namely, f (R, T) gravity, for which R and T stand for the Ricci scalar and trace …

Context. Millisecond pulsars (MSPs) are generally believed to be old neutron stars (NSs),
formed via type Ib/c core-collapse supernovae (SNe), which have been spun up to high …

We set up the general formalism to model polytropic Newtonian stars with anisotropic
pressure. We obtain the corresponding Lane-Emden equation. A heuristic model based on …

We analyze in detail conformally flat spherically symmetric fluid distributions, satisfying a
polytropic equation of state. Among the two possible families of relativistic polytropes, only …

In recent years, the idea of sub-and super-Chandrasekhar limiting mass white dwarfs (WDs),
which are potential candidates to produce under-and over-luminous type Ia supernovae …

Recent observations of type Ia supernovae (SNe Ia) have discovered a subclass of" super-
Chandrasekhar" SNe Ia (SC SNe Ia) whose high luminosities and low ejecta velocities …

Modified gravity theories can introduce modifications to the Poisson equation in the
Newtonian limit. As a result, we expect to see interesting features of these modifications …

We present the nonrelativistic limit of the stellar structure equations of Ricci-based gravities,
a family of metric-affine theories whose Lagrangian is built via contractions of the metric with …
