Construction of 3D wormhole supported by phantom energy
In this article, we have found a series solution of 3D Einstein equations
describing a wormhole for an inhomogeneous distribution of phantom energy.
Here, we assume equation of state is linear but highly anistropic.Comment: 9 papge, 4 figures. Accepted for publication in Physica Script
Compact stars in gravity
In the present paper we generate a set of solutions describing the interior
of a compact star under theory of gravity which admits conformal
motion. We consider the equation of state (EOS) with
for the fluid distribution consisting normal matter,
being the EOS parameter. We therefore explore several aspects of the model
analytically along with graphical representations to check the physical
validity as well as acceptability of it within specified observational
constraint in connection to a dozen of the compact star candidates. It is shown
from the presented model that these objects are nothing but radiating compact
stars.Comment: 16 pages, 6 figures, 1 table, substantial modification based on
