Zhaohuan Zhu, speaking in the Institute for Advanced Study's astrophysics seminar series, argues that magnetospheric accretion is a single physical process repeating across wildly different astronomical objects, from neutron stars and white dwarfs to young stellar objects and planets. He connects the mechanism to X-ray pulsars and ultra-luminous X-ray sources on one end and ultraviolet excess and atomic emission lines in young stars on the other, tracing both back to magnetic field dynamics. Zhu presents first-principle three-dimensional magnetohydrodynamic simulations his group has run, walking through filamentary accretion caused by interchange instability, magnetic bubbles resembling MAD disk states, star-disk torque, field inflation, magnetic reconnection, and episodic outflows. He closes by connecting these accretion dynamics to exoplanet demographics, linking a theoretical plasma mechanism to observable planet populations. The talk runs just over an hour and is pitched at a research seminar audience familiar with MHD.
