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…
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…
Spirals, rings, and vortices shaped by shadows in protoplanetary disks: from radiative hydrodynamical simulations to observable signatures
Alexandros Ziampras, Cornelis P. Dullemond, Tilman Birnstiel +2
Numerous protoplanetary disks exhibit shadows in scattered light observations. These shadows are typically cast by misaligned inner disks and are associated with observable structu…
A Particle-based Approach to Dust Dynamics in External Photoevaporative Winds
S. Paine, T. J. Haworth, R. P. Nelson
Planet-forming discs in sufficiently strong UV environments lose gas in external photoevaporative winds. Dust can also be entrained within these winds, which has consequences for t…
Dusty substructures induced by planets in ALMA disks: how dust growth and dynamics changes the picture
Alexandros Ziampras, Prakruti Sudarshan, Cornelis P. Dullemond +4
Protoplanetary disks exhibit a rich variety of substructure in millimeter continuum emission, often attributed to unseen planets. As these planets carve gaps in the gas, dust parti…
