Buoyancy response of a disk to an embedded planet: a cross-code comparison at high resolution
Alexandros Ziampras, Sijme-Jan Paardekooper, Richard P. Nelson
In radiatively inefficient, laminar protoplanetary disks, embedded planets can excite a buoyancy response as gas gets deflected vertically near the planet. This results in vertical…
Measuring the Numerical Viscosity in Simulations of Protoplanetary Disks in Cartesian Grids -- The Viscously Spreading Ring Revisited
Jibin Joseph, Alexandros Ziampras, Lucas Jordan +2
Hydrodynamical simulations solve the governing equations on a discrete grid of space and time. This discretization causes numerical diffusion similar to a physical viscous diffusio…
Modeling planet-induced gaps and rings in ALMA disks: the role of in-plane radiative diffusion
Alexandros Ziampras, Richard P. Nelson, Roman R. Rafikov
ALMA observations of protoplanetary disks in dust continuum emission reveal a variety of annular structures. Attributing the existence of such features to embedded planets is a pop…
