Astrochemistry of AGB Stars: Chemical Processes in Circumstellar Envelopes

MonashPhysicsAndAstronomy via YouTube

Overview

Learn about the complex chemistry of AGB star envelopes in this research presentation that challenges traditional understanding of stellar chemical processes. Explore how recent astronomical observations have revealed unexpected molecular abundances that deviate from chemical equilibrium predictions. Discover how high-resolution ALMA observations are providing new insights into molecular distribution near AGB stars, while single-dish observations have identified diverse metal-bearing molecules in outer circumstellar layers. Examine the evolving paradigm of stellar surface chemistry, from equilibrium conditions to ultraviolet photon processing in outer layers, and understand the current challenges facing chemical models in explaining these new discoveries.
