Astrophysical and Planetary Sciences Colloquium
Monday, October 18, 2021 at 12:40 JILA Auditorium and https://cuboulder.zoom.us/j/96468671083 Richard Frazin, University of Michigan "Frontiers in Direct Imaging of Exoplanets" Abstract:I will provide an overview of some of the science drivers of direct imaging of exoplanets and then provide a brief survey of the observational efforts involving stellar coronagraphy. The need for treating hardware optical aberrations is highlighted. In ground-based direct imaging, the most promising methods for imaging and correcting the hardware aberrations are based on stellar coronagraphy and "freezing" the atmospheric turbulence, which requires kHz frame rates. I explain the concepts involved and discuss plans for implementation.
