Dr. Jessie Christiansen, from NASA's Exoplanet Science Institute, will speak on the topic of "From Kepler to the Habitable Worlds Observatory: The Emerging Picture of Planet Populations." 

An abstract of her talk follows:  Currently, no single exoplanet detection technique is sensitive to planets across their full dynamic range of size and separation. However, the systems probed by each technique complement each other neatly. I will walk through the progress of the Kepler occurrence rate calculations, including our current understanding of eta_Earth, the frequency of Earth-like planets, and its implications for NASA’s next flagship mission, the Habitable Worlds Observatory. I will present our new results from K2 and TESS, extending the Kepler occurrence rates along stellar age, metallicity, and Galactic sub-population axes, and the implications for planet formation and evolution theories. Finally, I will highlight the larger demographics puzzle - exploring occurrence rate results from the other techniques that probe different stellar and exoplanet regimes - and the progress to be made working to join those pieces together.
