RESEARCH INTERESTS

As an early Master's student, my research interests are broad, but I am particularly drawn to Astronomy and Astrophysics. Below is a brief overview of my current interests, though I am eager to expand my understanding into interdisciplinary topics as well.

MHD Simulations

Astrophysical Fluid Dynamics (MHD, rMHD, GRMHD)

Fluid dynamics plays a crucial role in various astrophysical environments, from solar plasma to accretion disks around black holes and neutron stars. Beyond astrophysics, numerical fluid dynamics also has applications in climate studies and industrial processes.

My primary exposure has been through MHD simulations while studying Solar Spicules, using the well-known PLUTO CODE. This research also led me to explore solar flares, coronal mass ejections (CMEs), and varous other properties that can led to the formation of these ubiquitous structures.

I am actively expanding my knowledge in Computational Fluid Dynamics (CFD) through different pipelines, besides Python-based approaches.

General Relativity

General Relativity, Binary Mergers, Shocks and PIC Simulations

General Relativity (GR) is one of the most fascinating subjects in physics, filled with open questions awaiting exploration. My interest lies at the intersection of GR and MHD simulations, particularly in the context of Binary Black Hole (BBH) and Binary Neutron Star (BNS) mergers.

Currently, I am exploring the Particle in Cell Simulations to analyse the Relativistic Collisonless Shcoks that can eventually lead to the formation of GRBs originating from such mergers.

Buchdahl Stars

Buchdahl Stars

Not much has been researched when it comes to Buchdahl Stars, but for some reason this has always peeked my interest. It is belived to be the newest addition in the category of compact objects after WDs, NSs and BHs, if they are ever observed succesfully.

BSs are believed to be that dead stars which has the maximum compactness while still pertaining a timelike boundary, i.e., star at the Buchdahl limit of M/R=4/9. It has the compactness greater than that of Neutron Stars but slighlty smaller than the Black holes. A static BS can be defined using the Schwarszchild metric even though it doesn't has any Event Horizon.

It is indeed one of the most interesting topics to be explored upon and in the future, I would like to delve deeper into the integrity of its internal structure.
