Noncommutative black hole in the Finslerian spacetime
Sourav Roy Chowdhury, Debabrata Deb, Farook Rahaman +2
We study the behavior of the noncommutative radiating Schwarzschild black hole in the Finslerian spacetime. The investigation shows that black hole possesses either (i) two horizon…
Compact star in Tolman Kuchowicz spacetime in background of Einstein Gauss Bonnet gravity
Piyali Bhar, Ksh. Newton Singh, Francisco Tello-Ortiz
The present work is devoted to the study of anisotropic compact matter distributions within the framework of 5-dimensional Einstein-Gauss-Bonnet gravity. To solve the field equatio…
Charged compact star model in Einstein-Maxwell-Gauss-Bonnet gravity
Piyali Bhar, Megan Govender
Present paper provides a model of static charged anisotropic fluid sphere in the EinsteinMaxwell- GaussBonnet (EMGB) theory of gravitation. We select KB anstz as the metric co-effi…
Compact stars: a generalized model
S. K. Maurya, Debabrata Deb, Saibal Ray +1
This paper discusses a generalized model for compact stars, assumed to be anisotropic in nature due to the spherical symmetry and high density. After embedding the four-dimensional…
A charged anisotropic well-behaved Adler-Finch-Skea solution Satisfying Karmarkar Condition
Piyali Bhar, Ksh. Newton Singh, Farook Rahaman +2
In the present article, we discover a new well-behaved charged anisotropic solution of Einstein-Maxwell's field equations. We ansatz the metric potential of the form given…
Generalized model for anisotropic compact stars
S. K. Maurya, Y. K. Gupta, Saibal Ray +1
In the present investigation an exact generalized model for anisotropic compact stars of embedding class one is sought for under general relativistic background. The generic soluti…
Kantowski-Sachs Universe in the Varying Speed of Light Theory
G. S. Khadekar, Arti Ghogre, Saibal Ray
In this work we consider the Kantowski-Sachs (KS) universe in the framework of varying speed of light theory. We present the general solutions of the gravitational field equations…
A review of the neutrino emission processes in the late stages of the stellar evolutions
Indranath Bhattacharyya
In this paper the neutrino emission processes being supposed to be the main sources of energy loss in the stellar core in the later stages of stellar evolution are reviewed. All th…
Exact Radiation Model For Perfect Fluid Under Maximum Entropy Principle
Abdul Aziz, Sourav Roy Chowdhury, Debabrata Deb +3
We find the Euler-Lagrangian equation by maximising the total entropy. Hence we obtain an expression for mass of the spherically symmetric system by solving the Euler-Lagrangian eq…
Possible existence of wormholes in the central regions of halos
Farook Rahaman, P. Salucci, P. K. F. Kuhfittig +2
An earlier study [Rahaman et al. (2014) & Kuhfittig (2014)] has demonstrated the possible existence of wormholes in the outer regions of the galactic halo, based on the Navarro-Fre…
Possible features of galactic halo with electric field and observational constraints
Koushik Chakraborty, Farook Rahaman, Saibal Ray +2
Observed rotational curves of neutral hydrogen clouds strongly support the fact that galactic halo contains huge amount of nonluminous matter, the so called gravitational dark matt…
A Dark Energy Model in Kaluza-Klein Cosmology
Utpal Mukhopadhyay, Ipsita Chakraborty, Saibal Ray +1
We study a dynamic model with varying gravitational constant under the Kaluza-Klein cosmology. Physical features and the limitations of the present model have been explored…
Inflationary phase and role of dark energy: Revisited
Indranath Bhattacharyya, Saibal Ray, Prasenjit Paul
The inflationary phase of the Universe is explored by proposing a toy model related to the scalar field, termed as {\it inflaton}. The potential part of the energy density in the s…
Singularity-free solutions for anisotropic charged fluids with Chaplygin equation of state
Farook Rahaman, Saibal Ray, Abdul Kayum Jafry +1
We extend the Krori-Barua analysis of the static, spherically symmetric, Einstein-Maxwell field equations and consider charged fluid sources with anisotropic stresses. The inclusio…
Variable Equation of State for Generalized Dark Energy Model
Saibal Ray, Farook Rahaman, Utpal Mukhopadhyay +1
We present a model for the present accelerating Universe and focus on the different important physical variables involved in the model under the phenomenological assumption $Λ\prop…
