MRI-triggered instability at the inner dead zone edge: disc evolution and burst modes tied to magnetic field strengths
Michael Cecil, Mario Flock, Daniel Steiner
The inner edge of the dead zone (DZIE) in protoplanetary discs is prone to episodic instability caused by the activation of the magneto-rotational instability (MRI) in the weakly t…
The effect of variable stellar magnetic fields on the spin state of T Tauri stars
Lukas Gehrig, Daniel Steiner
Understanding the stellar spin evolution of young stars is crucial for understanding the evolution of protoplanetary disks and, consequently, the formation of exoplanets. According…
Time-dependent, long-term hydrodynamic simulations of the inner protoplanetary disk I: The importance of stellar magnetic torques
D. Steiner, L. Gehrig, B. W. Ratschiner +4
We conduct simulations of the inner regions of protoplanetary disks (PPDs) to investigate the effects of protostellar magnetic fields on their long-term evolution. We use an inner…
1+1D implicit disk computations
Florian Ragossnig, Ernst A. Dorfi, Bernhard Ratschiner +4
We present an implicit numerical method to solve the time-dependent equations of radiation hydrodynamics (RHD) in axial symmetry assuming hydrostatic equilibrium perpendicular to t…
Mass limits for stationary protoplanetary accretion disks
Florian Ragossnig, Lukas Gehrig, Ernst A. Dorfi +2
The collapse of interstellar gaseous clouds towards a protostar leads to the formation of accretion disks around the central star. Such disks can be dynamically stable if they sett…
Time-dependent galactic winds
E. A. Dorfi, D. Steiner, F. Ragossnig +1
Cosmic rays (CRs) are transported out of the galaxy by diffusion and advection due to streaming along magnetic field lines and resonant scattering off self-excited Magneto-Hydro-Dy…
Interaction of infalling solid bodies with primordial atmospheres of disk-embedded planets
Florian Ragossnig, Alexander Stökl, Ernst Dorfi +3
Planets that form early enough to be embedded in the circumstellar gas disk accumulate thick atmospheres of nebular gas. Models of these atmospheres need to specify the surface lum…
