| The goal of the thesis is to significantly develop understanding of the theory and observational implications of two stars undergoing strong interaction or a merger. Depending on the interests of the student, the work will focus on understanding unusual transients likely associated with binary star interactions, transients from stellar collisions, formation of dust and molecules in binary interactions, and understanding the observational implications of the theory (blue stragglers, R CrB stars, FK Com stars, eta Car, progenitor of SN1987A, etc.). In addition to analytic or semi-analytic work, the thesis can utilize existing codes or codes under development in the group: 1D stellar evolution, smoothed particle (radiation)hydrodynamics, moving mesh radiation hydrodynamics, or N-body calculations. In addition, the group is a member of All-Sky Automated Survey for Supernovae (ASAS-SN), and the thesis can include significant observational or data analysis component from ASAS-SN or other photometric or spectroscopic surveys (APOGEE, Gaia, TESS). |

| There is now renewed interest in the evolution and death of binary stars connected with the detection of gravitational waves from double compact objects and the exploration of new time-domain phenomena. |
