Reconstructing FHDE with Scalar and Gauge Fields
Ayush Bidlan, Paulo Moniz, Oem Trivedi
We revisit the Fractional Holographic Dark Energy (FHDE) model to reconstruct it by means of dynamic candidates such as () Quintessence, () K-essence, () Dilaton, (…
Stability of Neutron Star and Cosmological Constant
Naveen K. Singh, Gopal Kashyap
We derive the equation for pressure within a neutron star, taking into account a non-zero cosmological constant (). We then examine the stability of the neutron star's equilibri…
Fractional Holographic Dark Energy
Oem Trivedi, Ayush Bidlan, Paulo Moniz
Holographic dark energy theories present a fascinating interface to probe late-time cosmology, as guided by contemporary ideas about quantum gravity. In this work, we present a new…
Photon sphere and shadow of a time-dependent black hole described by a Vaidya metric
Jay Solanki, Volker Perlick
In this paper we derive exact analytical formulas for the evolution of the photon sphere and for the angular radius of the shadow in a special Vaidya spacetime. The Vaidya metric d…
Gravitational collapse of compact stars in gravity
Jay Solanki
Model of gravitational collapse of anisotropic compact stars in a new theory of gravity has been developed. The author considers the modified gravity model of $ f(R) = ξR^…
Gravitational Collapse of Anisotropic Compact Stars in Modified Gravity
Jay Solanki
The physically realistic model of compact stars undergoing gravitational collapse in gravity has been developed. We consider a more general model …
A study on the Friedmann like Universe with Torsion using Noether Symmetry
Ramkumar Radhakrishnan
This paper deals with the symmetry analysis of the Einstein Cartan theory which is an extension of the General Relativity and it accounts for the space-time torsion. We begin by ap…
Shadows and precession of orbits in rotating Janis-Newman-Winicour spacetime
Divyesh N. Solanki, Parth Bambhaniya, Dipanjan Dey +2
In this paper, we construct the rotating Janis-Newman-Winicour (JNW) naked singularity spacetime using Newman-Janis Algorithm (NJA). We analyse NJA with and without complexificatio…
A New Class of Analytical Solutions Describing Anisotropic Neutron Stars in General Relativity
Jay Solanki, Bhashin Thakore
A new class of solutions describing analytical solutions for compact stellar structures has been developed within the tenets of General Relativity. Considering the inherent anisotr…
Analytical Stellar Models of Neutron Stars in Teleparallel Gravity
Jay Solanki, Rohan Joshi, Malay Garg
In this paper, we developed three analytical models and obtained a new class of solutions describing compact stellar structures using the theory of teleparallel gravity. We conside…
Post-Newtonian properties of EMRI with Power Law Potential
Chinmay N. Gandevikar, Divyesh N. Solanki, Dipanjan Dey
There are many astrophysical scenarios where extreme mass ratio inspiral (EMRI) binaries can be surrounded by matter distribution. The distribution of mass can affect the dynamical…
Precession of timelike bound orbits in Kerr spacetime
Parth Bambhaniya, Divyesh N. Solanki, Dipanjan Dey +3
Astrometric observations of S-stars provide a unique opportunity to probe the nature of Sagittarius-A* (Sgr-A*). In view of this, it has become important to understand the nature a…
