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 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 2019
Neutron stars are some of the densest objects in the Universe, with densities in their cores that are larger than that of the atomic nucleus. Their relatively small size allows them to spin very rapidly, with speeds at the equator that are a large fraction of the speed of light. Being some of the...

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...

Neutron stars are interesting due to their extremely large densities (∼ 1015 g/cm^3), and also because the accretion of matter from a companion star can spin them up to very high frequencies (∼716 Hz based on observations ). When we study black holes (BH), the only thing that we have to worry...

Fall 2023
We examine the long-term evolution of accretion tori around the remnants of compact object mergers and the explosions of highly magnetized massive stars to better understand their roles in the creation of optical transients and the synthesis of r-process elements. We begin by modifying the...
