Hi, I am
Abha Vishwakarma
I am an astronomy Ph.D. student in the Department of Astronomy at the University of Illinois Urbana-Champaign, United States. I am interested in the dynamics of compact objects, such as accretion around neutron stars and black holes, and in the interactions of compact objects in binaries. I like compact objects because I love the theory of General Relativity and its applications in astrophysics. I am currently working with Prof. Paul Ricker on modelling accretion around Active Galactic Nuclei (black holes at the center of galaxies).
I graduated from the National Institute of Science Education and Research, India, in 2024 with a master's in physics. My master's thesis was on the Gravitational Wave emission from Neutron stars undergoing Common Envelope Evolution. Common Envelope (CE) systems are binaries in which one star (the primary) has reached a late stage of its evolution and expanded into a red giant, and the other star (the secondary) gets engulfed by this expanded envelope. Hence, the secondary and the primary core orbit each other within a shared envelope. I developed a CE module in the 1D stellar evolution code MESA to model the hydrodynamical expansion of the envelope during this phase. I compared my findings with a previous result that assumed a static envelope throughout the CE evolution.
Apart from physics, I am passionate about arts and crafts, and you can see some of my work in the creations tab. I love the outdoors, and I especially like to go hiking and trekking.
