Fall 2021
AR Sco is the first known white dwarf pulsar and currently there is no definitive model for its emission or evolution. This type of binary system could be a critical step in the formation of magnetic cataclysmic variables, a type of accreting white dwarf/M dwarf binary system. In this thesis, I...

Fall 2016
Low mass X-ray binaries (LMXBs) are systems of compact stellar remnants accreting from a low mass companion star. These systems show various levels of mass transfer on various timescales. Many aspects of accretion in these systems are still not fully understood, specifically the emission...

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,...

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...

Constraining the Physics of the X-ray Irradiated Accretion Discs in Low-mass X-ray Binaries with Observations
DownloadFall 2018
Recurring outbursts associated with matter flowing onto compact stellar remnants (black holes and neutron stars) in low-mass X-ray binary systems provide constraints on the poorly understood accretion process. Multi-wavelength light-curves and spectra of these bright outbursts provide powerful...

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...

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...

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...
