Lyα Scattering Models Trace Accretion and Outflow Kinematics in T Tauri Systems

T Tauri stars produce broad Ly α emission lines that contribute ∼88% of the total UV flux incident on the inner circumstellar disks. Ly α photons are generated at the accretion shocks and in the protostellar chromospheres and must travel through accretion flows, winds, and jets, the protoplanetary d...
