IvS Seminar: Daniel Pauli (30/01/2025)

Daniel Pauli - "Unraveling massive star and binary physics in the nearby low-metallicity galaxy, the Small Magellanic Cloud, as a proxy for high-redshift galaxies" (IvS seminar 30/01/2025)
Abstract: Typically massive stars are formed in binary systems, where they can interact with their companions, which significantly alters their evolution as well as their feedback. However, binary evolution, particularly at low metallicity, remains poorly understood. In this talk, I will present the recent discoveries of post-interaction binaries in the low-metallicity Small Magellanic Cloud galaxy. I will illustrate how the detailed multi-epoch and multi-wavelength spectral analysis, impacts our understanding of binary evolution and stellar winds. Finally, I will discuss the implications for our interpretation of the rest-frame UV spectra of high-redshift galaxies.
