The Influence of Dust Composition on Accretion Outbursts
Nicolas Kaufmann, Anna B. T. Penzlin, Alfie Robinson +3
Context: Episodic accretion outbursts have been shown to occur in protoplanetary discs due to thermal instability at the inner edge of the dead zone. These outbursts periodically h…
Planet formation at the inner edge of the dead zone II. Outbursts, rings, vortices, and suppression of planetesimal formation
Alexandros Ziampras, Tilman Birnstiel
Accretion outbursts have been observed in a variety of young stellar objects, but models of their dynamical evolution have been largely limited to axisymmetric models due to their…
Planet formation at the inner edge of the dead zone -- I. the interplay between accretion outbursts and dust growth
Alexandros Ziampras, Tilman Birnstiel, Nicolas Kaufmann +2
The inner edge of the dead zone in protoplanetary disks has been shown to periodically go unstable, leading to accretion outbursts and annular substructure within the dead zone. Wh…
TriPoDPy: 1D Tri-Population size distributions forDust evolution in protoplanetary disks
Nicolas Leo Kaufmann, Thomas Pfeil, Sebastian Stammler +3
TriPoDPy is a code simulating the dust evolution, including dust growth and dynamics in protoplanetary disks using the parametric dust model presented in (Pfeil et al., 2024). The…
General Implicit Runge-Kutta Integrators for Multifluid Gas-Dust Aerodynamic Drag
Giovanni Tedeschi-Prades, Til Birnstiel, Klaus Dolag +2
The integration of aerodynamic drag is a fundamental step in simulating dust dynamics in hydrodynamical simulations. We propose a novel integration scheme, designed to be compatibl…
Modeling dust dynamics in OpenGadget3 -- I. SPH implementation of the One-Fluid model
Giovanni Tedeschi-Prades, Til Birnstiel, Klaus Dolag +2
Dust dynamics plays a critical role in astrophysical processes and has been modeled in hydrodynamical simulations using various approaches. Among particle-based methods like Smooth…
