The Dynamics of Infall and Accretion Shocks in the Outer Disk
Susan Terebey, Loraine Sandoval Ascencio, Lizxandra Flores-Rivera +2
High-spatial-resolution observations of disks around young stars suggest planetary systems begin forming early, during the protostellar phase (< 1 Myr) when stars accrete most of t…
