Title: Multi-Wavelength Monitoring of the Young HMXB SN 2010da

Abstract: SN 2010da is an extremely young (<5 Myr) high mass X-ray binary, likely with a neutron star primary and a supergiant donor star. First detected as a "supernova impostor", SN 2010da offers a unique laboratory for studying the terminal stages of massive binary evolution; however, despite its established variability SN 2010da has not been regularly monitored in any wavelength regime. We have recently proposed an ongoing Swift X-ray+UV monitoring campaign during Swift Cycle 13. Here we propose for accompanying optical spectroscopy of SN 2010da with Gemini-S. We previously acquired a high-S/N optical spectrum of SN 2010da in quiescence during the 2016A semester. The observations we request here will allow us to model the outflow velocities, circumstellar environment, and eruptive history of the SN 2010da donor star, furthering our understanding of massive binary evolution.
