Interactions between stars are crucial for diverse areas of astrophysics, but they are not yet fully understood. These interactions come in forms as diverse as a direct physical collision, matter transfer from one star to another, and a "common envelope" (CE). The CE phase is a short period of...

We present an intensive radio and X-ray monitoring campaign on the 2009 outburst of the Galactic black hole candidate X-ray binary H1743−322. With the high angular resolution of the Very Long Baseline Array, we resolve the jet ejection event and measure the proper motions of the jet ejecta...

We present simultaneous radio through sub-mm observations of the black hole X-ray binary (BHXB) V404 Cygni during the most active phase of its June 2015 outburst. Our 4 h long set of overlapping observations with the Very Large Array, the Sub-millimeter Array and the James Clerk Maxwell Telescope...

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...

We present Atacama Large Millimetre/Sub-Millimetre Array (ALMA) observations of IRAS 19132+1035, a candidate jet–interstellar medium (ISM) interaction zone near the black hole X-ray binary (BHXB) GRS 1915+105. With these ALMA observations (combining data from the 12 m array and the Atacama...

We explore the production and observation of high energy (X-ray and ultraviolet/UV) radiation in the context of Galactic, compact binary systems. At the end of the stellar lifecycle, a star collapses into one of three compact objects (COs) depending on the mass at the time of collapse: a white...

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...

In astrophysics, stellar evolution is one of the most discussed topics. Although a significant amount of research and advancement of instrumentation over the last few decades have contributed to this field greatly, our understanding of the pre-main sequence evolution remains largely incomplete....
