Starlight-driven flared-staircase geometry in radiation hydrodynamic models of protoplanetary disks
Prakruti Sudarshan, Mario Flock, Alexandros Ziampras +2
Protoplanetary disks observed in millimeter continuum and scattered light show a variety of substructures. Various physical processes in the disk could trigger such features -- one…
Sculpting protoplanetary discs -- modelling circumbinary cavities at observable scales with radiation hydrodynamics
Anna B. T. Penzlin, Alexandros Ziampras, Nicolas T. Kurtovic +2
Observations of circumbinary discs reveal inner cavities, with their shape and size varying strongly between different systems. The structure of the cavity is determined by the com…
How two-dimensional are planet--disc interactions? I. Locally isothermal discs
Amelia J. Cordwell, Alexandros Ziampras, Joshua J. Brown +1
Planet--disc interactions, despite being fundamentally three-dimensional, are often studied in the two-dimensional `thin-disk' approximation. The overall morphology of planet--disc…
How two-dimensional are planet-disc interactions? II. Radiation hydrodynamics and suitable cooling prescriptions
Alexandros Ziampras, Amelia J. Cordwell, Roman R. Rafikov +1
The ring and gap structures found in observed protoplanetary disks are often attributed to embedded gap-opening planets and typically modeled with simplified thermodynamics in the…
Turbulence in protoplanetary disks: A systematic analysis of dust settling in 33 disks
M. Villenave, G. Rosotti, M. Lambrechts +7
The level of dust vertical settling and radial dust concentration in disks is of critical importance for understanding the efficiency of planet formation. We present the first unif…
Halting the migration of super-Earths by efficient gap opening in radiative, low viscosity disks
Alexandros Ziampras, Richard P. Nelson, Sijme-Jan Paardekooper
While planet migration has been extensively studied for classical viscous disks, planet-disk interaction in nearly inviscid disks has mostly been explored with greatly simplified t…
