Transition disks and planetary systems
01/05/2018 to 30/04/2021
Abstract / short description:
Transitional disks (TDs) presumably occur in the later phases of the evolution of protostellar disks around young stars and show a depletion of flux from the inner, central parts of the disk. One variety of such disks display a lack of radiation in the mid-infrared wavelength regime which is interpreted as large inner holes in their dust distribution. Nevertheless they show significant gas accretion signatures coming from the central inner region.
It has been suggested that for these type of TDs this inner cavity might be created by the presence of one or more planets that cleared out the inner disk region. In this project we shall follow this line of thought and will perform multi-dimensional hydrodynamic studies to clarify the dynamical impact of planets on TDs in order to prove (or disprove) the existence of planets in such disks. The studies will include gas dynamics, dust particles, embedded planets, radiation transport and irradiation from the central star.
