Astronomy was a culturally prominent practice during the nineteenth century in Britain. In this thesis I examine the development of astronomy in one area, Wales. Astronomy became an important subject in the lecturing industry that emerged during the century as lecturers promoted astronomical...

Neutron stars provide the key to understanding the equation of state at the highest pressure and density. Constraining the mass-radius relation of neu- tron stars will provide opportunities to test the currently conflicting candidates for the equation of state. Next generation instruments, such...

Neutron stars (NSs) are some of the densest objects in the universe. In this thesis, I focus on studying X-ray thermal emission from neutron stars, using X-ray observations of different varieties of NSs. X-ray observations can put constraints on the mass and radius of NSs, and thus on density and...

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...

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...

Star formation drives secular galaxy evolution by linking stars and gas in galaxies. This link forms part of the "baryonic cycle," where stars form from interstellar gas, and a portion of that gas is returned to the interstellar medium upon the star’s death. Understanding the baryonic cycle and...

Concerns over the environmental impacts of thermal production methods for bitumen and heavy oil have led to the exploration of alternative technologies including solvent-assisted production methods. While solvent-assisted production methods have been studied extensively, apparent diffusion rates...

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 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...
