Dynamical Impacts of Accretion Streamers on Protoplanetary Disks
Han-Gyeol Yun, Jeong-Eun Lee, Jaehan Bae +1
Recent observations suggest that accretion streamers are common in protoplanetary disks, yet their dynamical impact on disk evolution remains poorly understood. Using three-dimensi…
Vertical Shear Instability in Thermally-Stratified Protoplanetary Disks: II. Hydrodynamic Simulations and Observability
Han-Gyeol Yun, Woong-Tae Kim, Jaehan Bae +1
We conduct three-dimensional hydrodynamic simulations to investigate the nonlinear outcomes and observability of vertical shear instability (VSI) in protoplanetary disks. Our model…
Vertical Shear Instability in Thermally-Stratified Protoplanetary Disks: I. A Linear Stability Analysis
Han-Gyeol Yun, Woong-Tae Kim, Jaehan Bae +1
Vertical shear instability (VSI), driven by a vertical gradient of rotational angular velocity, is a promising source of turbulence in protoplanetary disks. We examine the semi-glo…
Effects of Radiative Diffusion on the Dynamical Corotation Torque in Three-Dimensional Protoplanetary Disks
Han-Gyeol Yun, Woong-Tae Kim, Jaehan Bae +1
The dynamical corotation torque arising from the deformation of the horseshoe orbits, along with the vortensity gradient in the background disk, is important for determining orbita…
Properties of Density and Velocity Gaps Induced by a Planet in a Protoplanetary Disk
Han Gyeol Yun, Woong-Tae Kim, Jaehan Bae +1
Gravitational interactions between a protoplanetary disk and its embedded planet is one of the formation mechanisms of gaps and rings found in recent ALMA observations. To quantify…
