Are protoplanetary disks born with vortices? -- Rossby wave instability driven by protostellar infall

Jaehan Bae, Lee Hartmann, Zhaohuan Zhu

We carry out two-fluid, two-dimensional global hydrodynamic simulations to test whether protostellar infall can trigger Rossby wave instability (RWI) in protoplanetry disks. Our re…
