Characterizing the Galactic Double White Dwarf Population - Na'ama Hallakoun, Valeriya Korol

Explore the Galactic double white dwarf population in this 30-minute conference talk from the "White Dwarfs from Physics to Astrophysics" KITP online conference. Delve into the latest findings on these abundant stellar remnants using data from astrometric, photometric, and spectroscopic all-sky surveys. Discover how white dwarfs serve as probes for various astrophysical phenomena, including star and planet formation, Galactic star formation rates, and low-frequency gravitational wave sources. Examine improved models of electron-degenerate stars and their reliance on advanced input physics. Gain insights into the state-of-the-art research, current model limitations, and new scientific opportunities arising from recent data. Learn about the Delta RVmax distribution, measurement errors, and results from the Projector and Spy surveys. Explore LISA frequency coverage, angular parameters, and comparisons with double Edwards. Conclude with a discussion on binary population synthesis and its implications for our understanding of the Galactic double white dwarf population.
