A New Class of Anisotropic Charged Compact Star
B. S. Ratanpal, Piyali Bhar
A new model of charged compact star is reported by solving the Einstein-Maxwell field equations by choosing a suitable form of radial pressure. The model parameters , , $p_…
Wormhole supported by dark energy admitting conformal motion
Piyali Bhar, Farook Rahaman, Tuhina Manna +1
In this article, we study the possibility of sustaining a static and spherically symmetric traversable wormhole geometries admitting conformal motion in Einstein gravity, which pre…
Dark energy stars: Stable configurations
Piyali Bhar, Tuhina Manna, Farook Rahaman +1
In present paper a spherically symmetric stellar configuration has been analyzed by assuming the matter distribution of the stellar configuration is anisotropic in nature and compa…
A comparative study between EGB gravity and GTR by modelling compact stars
Piyali Bhar, Megan Govender, Ranjan Sharma
In this paper we utilise the Krori-Barua ansatz to model compact stars within the framework of Einstein- Gauss-Bonnet (EGB) gravity. The thrust of our investigation is to carry out…
Modeling Anisotropic Stars Obeying Chaplygin Equation of State
Piyali Bhar, Megan Govender, Ranjan Sharma
In this work we provide a framework for modeling compact stars in which the interior matter distribution obeys a generalised Chaplygin equation of state. The interior geometry of t…
A new solution of embedding class I representing anisotropic fluid sphere in general relativity
Ksh. Newton Singh, Piyali Bhar, Neeraj Pant
In the present paper we are willing to model anisotropic star by choosing a new grr metric potential. All the physical parameters like the matter density, radial and transverse pre…
Modelling of anisotropic compact stars of emebedding class one
Piyali Bhar, S. K. Maurya, Y. K. Gupta +1
In the present article, we have constructed static anisotropic compact star models of Einstein field equations for the spherical symmetric metric of embedding class one. By assumin…
Charged Perfect Fluid Sphere in Higher Dimensional Spacetime
Piyali Bhar, Tuhina Manna, Farook Rahaman +2
Present paper provides a new model for perfect fluid sphere filled with charge in higher dimensional spacetime admitting conformal symmetry. We consider a linear equation of state…
