Disk evolution and the fate of water
Lee Hartmann, Fred Ciesla, Oliver Gressel +1
We review the general theoretical concepts and observational constraints on the distribution and evolution of water vapor and ice in protoplanetary disks, with a focus on the Solar…
Misaligned Disks in the Binary Protostar IRS 43
Christian Brinch, Jes K. Jørgensen, Michiel R. Hogerheijde +2
Recent high angular resolution (0.2") ALMA observations of the 1.1 mm continuum and of HCO+ J=3-2 and HCN J=3-2 gas towards the binary protostar IRS 43 reveal multiple Kepler…
Linear analysis of the vertical shear instability: outstanding issues and improved solutions (Research Note)
O. M. Umurhan, R. P. Nelson, O. Gressel
The Vertical Shear Instability is one of two known mechanisms potentially active in the so-called dead zones of protoplanetary accretion disks. A recent analysis indicates that a s…
Mean-field and direct numerical simulations of magnetic flux concentrations from vertical field
A. Brandenburg, O. Gressel, S. Jabbari +2
Strongly stratified hydromagnetic turbulence has previously been found to produce magnetic flux concentrations if the domain is large enough compared with the size of turbulent edd…
New scaling for the alpha effect in slowly rotating turbulence
A. Brandenburg, O. Gressel, P. J. Käpylä +3
Using simulations of slowly rotating stratified turbulence, we show that the alpha effect responsible for the generation of astrophysical magnetic fields is proportional to the log…
