Fall 2021
In this thesis, we investigate the effectiveness of theoretical descriptions of angular momentum loss in stars due to the presence of magnetic fields, a process commonly known as magnetic braking. The most widely used description of magnetic braking is the so-called Skumanich prescription, which...

Spring 2021
I present the formation and evolution of the shock wave driven by neutrino losses in failed core-collapse supernovae that form black holes (BHs). Neutrino losses result in a decrease in the gravitational mass, which leads to the formation of an outward shock. The ejected mass and energy vary...

Constraining the physics of relativistic jets with radio through (sub-)millimetre properties of X-ray binaries
DownloadFall 2018
Astrophysical jets are ubiquitous phenomena in our universe, linked to a wide range of objects, from young stars to black holes. These powerful, highly collimated outflows deposit significant amounts of energy and matter into the surrounding medium, affecting star formation, galaxy evolution, and...

The Definitive All-Sky Observational Study Of Accretion Disc Physics In Galactic Black Hole X-ray Binaries
DownloadFall 2014
Stellar mass black holes (BHs) accreting in binary systems provide valuable insight into how binary systems evolve and how mass is transferred via accretion. Although in recent years a canonical picture of the outburst evolution in black hole X-ray binaries (BHXRBs) has emerged, these systems...

Constraining the Jet Properties of the New Transient X-ray Binary, Swift J1745-26, With the Submillimeter Array and James Clerk Maxwell Telescope
DownloadFall 2014
Accreting astrophysical sources are an important end-result of intricate stellar dynamics. A particularly puzzling aspect of this accretion process is the production and evolution of plasma outflows (known as jets). Although astrophysical jets have been studied for decades in accreting sources,...

Fall 2014
We present the first combined optical/X-ray observation of a very faint transient X-ray binary (VFXT), M15 X-3. Chandra observations constrain the source to be < 10^34 erg/s in all observations. The X-ray spectrum shows evidence of curvature, and is best fit by a broken power law with break...

Fall 2017
In this thesis we investigate a novel binary formation channel with a semi- degenerate donor and examine the stability criteria in binary systems with a massive donor. First we will review the current basics in the understanding of binary systems along with where recent research has been moving...

Fall 2023
In the era of all-sky surveys, wide-area radio surveys like the Very Large Array Sky Survey (VLASS) place strong emphasis on the identification and classification of candidate transient events. To aid the transient searches, automatically generated VLASS Quick-Look (QL) images are designed and...

Exotic binaries in Galactic globular clusters: identification, classification, and their formation
DownloadFall 2021
Globular clusters (GCs) are dense and massive stellar populations, which provide a unique environment where the high stellar density facilitates frequent dynamical encounters, creating many exotic binaries. These exotic binaries generally have short orbits and often harbour compact objects,...

In this thesis we study MT from giant and subgiant donors in binary stars. We develop a MT simulation framework based on the MESA set of stellar libraries, which is suitable to study extremely high MT rates and predict the stability of MT. We find that the MT from giant donors is much more stable...
