Evidence for Strong Time-Variable Asymmetries at the Dust Destruction Front in Some Herbig Ae/Be Stars

This 17-minute conference talk by John Monnier from the University of Michigan presents evidence for strong time-variable asymmetries at the dust destruction front in some Herbig Ae/Be stars. Recorded during the "Planets on the Edge" conference at the Kavli Institute for Theoretical Physics (KITP) at UC Santa Barbara in May 2025, the presentation contributes to broader discussions about exoplanet formation and evolution. Explore research that helps address key questions about close-in rocky planets, including their nature and atmospheres, formation mechanisms, governing parameters across different star systems, and why our solar system lacks analogous planets. This talk is part of a conference bringing together experts in exoplanet demographics, protoplanetary disks, planet formation models, and meteoritics to synthesize current knowledge and advance understanding of inner protoplanetary disks and the Earth-sized planets that form within them.
