| dc.description.abstract | This project explores the phenomenon of Bondi-Hoyle-Lyttleton (BHL) accretion, which plays a crucial role in astrophysical processes such as star formation, accretion onto compact objects, and binary star evolution. The project also involves a computational part where the differences between populations of binary stars evolved under different prescriptions are studied.
The theoretical aspect of the project consists of two parts. First, the explanation of important properties of binary stars and binary interactions. Secondly, a review of relevant literature to gather the key aspects of the derivation of the analytical formula for the mass transfer in wind-fed binaries, which describes the rate at which material is accreted into a gravitating object from a surrounding medium, specifically in this project, wind-fed binary stars.
In the computational phase, different populations of binary stars are evolved with different prescriptions using POSYDON, and then the differences between these populations are studied to explore how the different prescriptions affect the evolution of the binary stars. | |
