Asymptotically stable numerical method for multispecies momentum transfer: gas and multifluid-dust test suite and implementation in FARGO3D
Pablo Benítez-Llambay, Leonardo Krapp, Martín E. Pessah
We present an asymptotically and unconditionally stable numerical method to account for the momentum transfer between multiple species. Momentum is conserved to machine precision.…
Dust segregation in Hall-dominated turbulent protoplanetary disks
Leonardo Krapp, Oliver Gressel, Pablo Benítez-Llambay +3
Imaging of the dust continuum emitted from disks around nearby protostars reveals diverse substructure. In recent years, theoretical efforts have been intensified to investigate ho…
On the dynamics of pebbles in protoplanetary disks with magnetically-driven winds
Mohsen Shadmehri, Fazeleh Khajenabi, Martin E. Pessah
We present an analytical model to investigate the production of pebbles and their radial transport through a protoplanetary disk (PPD) with magnetically driven winds. While most of…
Analytical Models of Exoplanetary Atmospheres. V. Non-gray Thermal Structure with Coherent Scattering
Gopakumar Mohandas, Martin E. Pessah, Kevin Heng
We apply the picket fence treatment to model the effects brought about by spectral lines on the thermal structure of irradiated atmospheres. The lines may be due to purely absorpti…
Characterizing the variable dust permeability of planet-induced gaps
Philipp Weber, Pablo Benítez-Llambay, Oliver Gressel +2
Aerodynamic theory predicts that dust grains in protoplanetary disks will drift radially inward on comparatively short timescales. In this context, it has long been known that the…
Orbital stability in static axisymmetric fields
Gopakumar Mohandas, Tobias Heinemann, Martin E. Pessah
We investigate the stability of test-particle equilibrium orbits in axisymmetric, but otherwise arbitrary, gravitational and electromagnetic fields. We extend previous studies of t…
