- 요약The lives, deaths, and afterlives of stars play a fundamental role in astrophysics. From planet formation and feedback in star-forming regions to galactic chemical evolution and gravitational wave progenitors, understanding stellar evolution is essential to understanding the observable Universe. A critical, but still very poorly understood, aspect of this topic is the impact of binarity on stellar evolution. While single stars follow evolutionary tracks set by their initial mass and metallicity, stars which interact with a binary stellar companion will have both their internal structures and global properties altered in ways unattainable through single star evolution. Unfortunately, the physics governing these interactions remains highly uncertain. However, we are uniquely poised to understand binary interaction and its impact on stellar evolution by combining recent advances in both observation and computation.Astronomy has entered an era of large surveys. The Gaia space telescope is collecting photometry, astrometry, and parallaxes for billions of stars. The Apache Point Observatory Galactic Evolution Experiment (APOGEE) as part of the Sloan Digital Sky Survey (SDSS) has collected spectroscopy for hundreds of thousands of stars. We also have long-baseline, time-series photometry for stars from Kepler and the Transiting Exoplanet Survey Satellite (TESS). On the computational front, advances in computing power have enabled us to run large grids of 1D stellar evolution models relatively cheaply. There are also a preponderance of 1D stellar evolution codes utilizing different numerical methods and imbued with different assumptions. These models and codes allow us to test individual physical assumptions and see how the evolution is changed.In my work, I leverage 1D stellar evolution models with stellar parameters from large surveys to study the effects of different types of interactions on the structure and evolution of stars of different masses. I first present an observational study of rotationally enhanced red giants, found via exploiting failure modes of APOGEE's spectroscopic processing pipeline. I identified a large population of interacting and post-interaction giants as well as a population of apparently single rotationally enhanced giants. I found two new failure modes of of the APOGEE pipeline as well.In the latter part of my dissertation I describe three modelling studies, examining the structural impacts of different interactions on massive stars due to the relationship between massive star structure and the ability to explode. I first present a grid of carbon-oxygen (CO) core models evolved from carbon ignition to core-collapse in order to fill in the late-stage evolution overlooked in binary population synthesis (BPS) codes. I reveal a complex landscape of final structures and present a prescription for use in BPS codes to predict explosion outcome based on the final structure of the core. I then apply this prescription to single and binary models from BPASS, and show how the structure-based prescription produces different neutron star and black hole mass distributions than the prescription based on CO-core mass commonly employed in BPS codes. Lastly, I present an ongoing study examining one particular interaction, an early case B merger, looking at long-term structural changes caused by merging as well as the differences by creating the merger product in two different ways.
