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...
Constraining the Physics of the X-ray Irradiated Accretion Discs in Low-mass X-ray Binaries with ObservationsDownload
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...
Constraining the physics of relativistic jets with radio through (sub-)millimetre properties of X-ray binariesDownload
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 BinariesDownload
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 TelescopeDownload
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,...
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...
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...
