Vertical shear instability in two-moment radiation-hydrodynamical simulations of irradiated protoplanetary disks II. Secondary instabilities and stability regions
Julio David Melon Fuksman, Mario Flock, Hubert Klahr
The vertical shear instability (VSI) is a hydrodynamical instability likely to produce turbulence in the dead zones of protoplanetary disks. Various aspects of this instability rem…
Vertical shear instability in two-moment radiation-hydrodynamical simulations of irradiated protoplanetary disks I. Angular momentum transport and turbulent heating
Julio David Melon Fuksman, Mario Flock, Hubert Klahr
We studied the linear and nonlinear evolution of the Vertical Shear Instability (VSI) in axisymmetric models of protoplanetary disks, focusing on the transport of angular momentum,…
Kinematic signatures of planet-disk interactions in VSI-turbulent protoplanetary disks
Marcelo Barraza-Alfaro, Mario Flock, Thomas Henning
Context. Planets are thought to form inside weakly ionized regions of protoplanetary disks, where turbulence creates ideal conditions for solid growth. However, the nature of this…
Probing the Temperature Structure of the Inner Region of a Protoplanetary Disk
Takahiro Ueda, Satoshi Okuzumi, Akimasa Kataoka +1
Midplane heating induced by disk accretion plays a key role in determining the disk temperature particularly at the inner disk midplane where planets form. However, the efficiency…
Meridional Circulation driven by Planetary Spiral Wakes in Radiative and Magnetized Protoplanetary Discs
Marco Cilibrasi, Mario Flock, Judit Szulágyi
We study a Jupiter-mass planet formation for the first time in radiative magneto-hydrodynamics (MHD) simulations and compare it with pure hydrodynamical simulations, as well as to…
The impact of dust evolution on the dead zone outer edge in magnetized protoplanetary disks
Timmy N. Delage, Matías Gárate, Satoshi Okuzumi +5
[Abridged] Aims. We provide an important step toward a better understanding of the magnetorotational instability (MRI)-dust coevolution in protoplanetary disks by presenting a proo…
