Observations of Polluted White Dwarfs - Siyi Xu

Explore a conference talk on observations of polluted white dwarfs presented by Siyi Xu from Gemini North. Delve into the latest findings from astrometric, photometric, and spectroscopic all-sky surveys that provide a comprehensive view of white dwarf populations in the Galaxy. Discover how these stellar remnants serve as valuable probes for various astrophysical phenomena, including star and planet formation, galactic star formation rates, and low-frequency gravitational wave sources. Examine the importance of improved models for electron-degenerate stars and the underlying physics required for accurate representations. Gain insights into the current state of white dwarf research, identify limitations in existing models, and explore new scientific opportunities arising from recent observational data. This 28-minute presentation is part of the "White Dwarfs from Physics to Astrophysics" conference held at the Kavli Institute for Theoretical Physics, bringing together experts in observational and theoretical white dwarf studies, fundamental physics, and astronomers utilizing white dwarfs as diagnostic tools.
