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…
Transit Ly- signatures of terrestrial planets in the habitable zones of M dwarfs
K. G. Kislyakova, M. Holmström, P. Odert +6
We modeled the transit signatures in the Lya line of a putative Earth-sized planet orbiting in the HZ of the M dwarf GJ436. We estimated the transit depth in the Lya line for an ex…
ALMA observations of the "fresh" carbon-rich AGB star TX Piscium. The discovery of an elliptical detached shell
Magdalena Brunner, Marko Mecina, Matthias Maercker +4
Aims. The carbon-rich asymptotic giant branch (AGB) star TX Piscium (TX Psc) has been observed multiple times during multiple epochs and at different wavelengths and resolutions, s…
