TALK ADDED - Protoplanetary disks (PPD) launch wind in various ways, including photoevaporation: the gas heated by irradiation from the central source may hence acquire sufficient energy to escape the potential well of the central star. Modeling photo-evaporation is challenging, thanks to the complication of chemical reactions and thermodynamic processes on the evaporation layer of a PPD. This talk presents the progress of our attempts in simulating FUV photoevaporation wind, with consistent hydrodynamics, radiation, and thermochemistry. Preliminary results suggest that microphysics is crucial to wind mass loss rate and other major characteristics of PPD photoevaporation.
