Project CircumDisk2 – The Dynamics of circumbinary Disks and embedded Planets

Basic data

Acronym:
CircumDisk2
Title:
The Dynamics of circumbinary Disks and embedded Planets
Duration:
01/05/2020 to 31/07/2020
Abstract / short description:
The majority of stars reside in binary star systems. During their
formation a sufficiently close binary star system is still surrounded by
a circumbinary disc from which material can be accreted onto the
binary. The orbital motion of the binary transfers angular momentum
to the disc and a central inner cavity forms. These cavities have been
directly detected in some special systems and the high spatial
resolution capabilities of ALMA will allow to investigate more of these
sources in even higher detail. A very active recent research topic is
the formation and evolution of planets in these discs inspired by the
circumbinary planets detected by the Kepler space mission. The
fundamental structure and dynamics of circumbinary discs and
embedded planets has been studied in the first phase of the project.
Here, we plan to perform new hydrodynamical simulations and study
the flow in the vicinity of stars, the accretion of mass and angular
momentum to the binary, the change of its orbit, the three-dimensional
structure of the disc and the spatial distribution of small particles. We
will collaborate closely with observers in order to analyse and interpret
upcoming new observations of discs and planets.
