Simulating the thermodynamics of gas, radiation, and multispecies dust: Method and applications to protoplanetary disks
Dhruv Muley, David Melon Fuksman, Prakruti Sudarshan +2
The thermodynamics of protoplanetary disks, governed by a complex interplay between gas, dust, and radiation, exerts a strong influence on their morphology and dynamics at both lar…
Just a Phase? Weakening Vertical Shear Instability Explains Class II Disk Morphologies: Simulations with dust coagulation, sedimentation, thermal relaxation, and backreaction
Thomas Pfeil, Alexandros Ziampras, Shangjia Zhang +2
The Vertical Shear Instability (VSI) is known to create turbulence and strong vertical mixing in protoplanetary disks if thermal relaxation is sufficiently fast. In simulations whe…
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…
Formation of multiple dust rings and gaps in protoplanetary discs by a single migrating planet II: radiative discs and observational signatures
Kim M. Weiskopf, Sören C. Meiners, Alexandros Ziampras +1
Dust structures in protoplanetary discs have been widely observed and their creation remains an active field of research. Several possible origins have already been explored, inclu…
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…
Substructure in externally irradiated protoplanetary disks, I. spirals and rings in two-dimensional radiation hydrodynamics
Alexandros Ziampras, Lin Qiao, Thomas J. Haworth
It is known that the external irradiation of protoplanetary disks by nearby massive stars can result in mass loss that impacts the disk evolution, however the dynamical impact of e…
The Circumbinary Disc of HD 34700A II. Analysis of a strong dust asymmetry
Daniele Fasano, Myriam Benisty, Jochen Stadler +8
ALMA observations have shown that substructures are ubiquitous in protoplanetary discs. A sub-group, the transition discs, shows large cavities and rings in dust continuum. Among t…
The role of detailed gas and dust opacities in shaping the evolution of the inner disc edge subject to episodic accretion
Michael Cecil, Mario Flock, Mykola G. Malygin +4
We investigate the effects of different dust and gas opacity descriptions on the structure and evolution of the inner regions of protoplanetary discs. The influence on the episodic…
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…
