An exact anisotropic star model with a linear barotropic equation of state and with Finch‐Skea potential is constructed within the framework of pure Lovelock gravity. A comparison with the corresponding Einstein model in a suitable limit is easily deduced. Evidently higher curvature effects induced by the Lovelock contributions generate lower densities, pressures, surface tensions, and anisotropy factors when compared to its Einstein counterpart. The maximum moment of inertia is attained for…

On surface tension for compact stars

In an earlier analysis it was demonstrated that general relativity gives higher values of surface tension in strange stars with quark matter than neutron stars. We generate the modified

Dynamical instability for radiating anisotropic collapse

We study the role played by local anisotropy and radiation (in the free-streaming regime) in the onset of dynamical instabilities. In the case of anisotropy we find that, for Newtonian and

A realistic stellar model based on an ansatz of Duorah and Ray

It is shown that the analytical stellar model of Duorah and Ray (1987) does not satisfy Einstein's field equations. All possible solutions derivable from the generalised density distribution are

Sound speeds, cracking and the stability of self-gravitating anisotropic compact objects

Using the concept of cracking we explore the influence that density fluctuations and local anisotropy have on the stability of local and non-local anisotropic matter configurations in general

The Dynamical Instability of Gaseous Masses Approaching the Schwarzschild Limit in General Relativity.

ABSTRACT In this paper the theory of the infinitesimal, baryon-number conserving, adiabatic, radial oscillations of a gas sphere is developed in the framework of general relativity. A variational

Newtonian and general relativistic contribution of gravity to surface tension of strange stars

Surface tension (S ) is due to the inward force experienced by particles at the surface and usually gravitation does not play an important role in this force. But in compact stars the gravitational

The trace-free Einstein equations and inflation

The trace-free version of the Einstein Gravitational equations, essentially equivalent to unimodular gravity, can solve the troubling issue of the huge discrepancy between quantum field theory

A theory of gravity

It is known that a slight generalization of the Newtonian theory of gravity is compatible with all present-day observations. This 'super-Newtonian' theory is not a complete theory of gravity, since

Dynamical instability in the collapse of anisotropic matter

The authors study the role played by local anisotropy in the onset of dynamical instabilities in self-gravitating systems. They determine that small anisotropies in the unperturbed system can
