Stability of coorbital planets around binaries

Stefan Adelbert, Anna B. T. Penzlin, Christoph M. Schäfer +3

In previous hydrodynamical simulations, we found a mechanism for nearly circular binary stars, like Kepler-413, to trap two planets in a stable 1:1 resonance. Therefore, the stabil…

Hydrodynamic turbulence in disks with embedded planets

Alexandros Ziampras, Wilhelm Kley, Richard P. Nelson

The vertical shear instability (VSI) is a source of hydrodynamic turbulence that can drive vigorous vertical mixing and moderate levels of accretion in protoplanetary disks, and it…

How cooling influences circumbinary discs

Prakruti Sudarshan, Anna B. T. Penzlin, Alexandros Ziampras +2

Circumbinary disc observations and simulations show large, eccentric inner cavities. Recent work has shown that the shape and size of these cavities depend on the aspect ratio and…

Binary orbital evolution driven by a circumbinary disc

Anna B. T. Penzlin, Wilhelm Kley, Hugo Audiffren +1

The question whether the interaction of a circumbinary disc with the central binary system leads to shrinking or expansion of the binary orbit has attracted considerable interest a…

Survival of planet-induced vortices in 2D disks

Thomas Rometsch, Alexandros Ziampras, Wilhelm Kley +1

Context: Several observations of protoplanetary disks display non-axisymmetric features, often interpreted as vortices. Numerical modeling has repeatedly shown that gap-opening pla…

Disks in close binary stars: γ-Cephei revisited

Lucas M. Jordan, Wilhelm Kley, Giovanni Picogna +1

Close binaries ( au) are known to harbor planets, yet planet formation is unlikely to succeed in such systems. Studying the dynamics of disks in close binaries can he…
