From thermal to magnetic driving: spectral diagnostics of simulation-based magnetothermal disc wind models
Michael L. Weber, Eleftheria Sarafidou, Christian Rab +2
Disc winds driven by thermal and magnetic processes are thought to play a critical role in protoplanetary disc evolution. However, the relative contribution of each mechanism remai…
Gravito-turbulent bi-fluid protoplanetary discs: 1. An analytical perspective to stratification
S. Rendon Restrepo, U. Ziegler, M. Villenave +1
Context. In Class 0/I and the outskirts of Class II circumstellar discs, the self-gravity of gas significantly affects the disc's vertical hydrostatic equilibrium. The contribution…
Global Hall-magnetohydrodynamic simulations of transition disks
Eleftheria Sarafidou, Oliver Gressel, Barbara Ercolano
Context. Transition disks (TDs) are a type of protoplanetary disk characterized by a central dust and gas cavity. The processes behind how these cavities are formed and maintained,…
Toward an efficient second-order method for computing the surface gravitational potential on spherical-polar meshes
Oliver Gressel, Udo Ziegler
Astrophysical accretion discs that carry a significant mass compared with their central object are subject to the effect of self-gravity. In the context of circumstellar discs, thi…
Hall-magnetohydrodynamic simulations of X-ray photoevaporative protoplanetary disc winds
Eleftheria Sarafidou, Oliver Gressel, Giovanni Picogna +1
Understanding the complex evolution of protoplanetary disks (PPDs) and their dispersal via energetic stellar radiation are prominent challenges in astrophysics. It has recently bee…
Alpha tensor and dynamo excitation in turbulent fluids with anisotropic conductivity fluctuations
Oliver Gressel, Günther Rüdiger, Detlef Elstner
A mean-field theory of the electrodynamics of a turbulent fluid is formulated under the assumption that the molecular electric conductivity is correlated with the turbulent velocit…
