Rings in protoplanetary disks: planets or ring instabilities?
Cornelis Dullemond (ZAH/ITA)
ITA "blackboard" Colloquium ( Hephysto link )
Philosophenweg 12, 106
Show/hide abstract

Abstract
The famous ALMA image of the disk around HL Tau shows that that protoplanetary disk consists of numerous concentric nearly perfect rings. In the mean time several new disk sources have revealed similar multi-ring patterns. These patterns have been interpreted by many astronomers as being caused by several low mass planets opening gaps in the disk. However, the planets themselves have not yet been detected, raising the possibility that perhaps these rings might have a completely different (and equally interesting) origin: that they are caused by disk-internal slow instabilities. The slowness is important, because a fast instability leads to a clumpy/turbulent disk. A sufficiently slow instability, however, can allow communication between gas parcels 360 degrees along their orbits, thus allowing density fluctuations to tidally smear out, coordinate and merge into rings. I will discuss two such potential instabilities, both related to the dust in the disk, and whether they might be at the origin of these rings.

Cosmic ray driven galactic winds and their dependence on halo mass
Jacob Svenja (H-ITS)
ITA "blackboard" Colloquium ( Hephysto link )
Philosophenweg 12, 106
Show/hide abstract

Abstract
Galactic winds are commonly observed in starburst galaxies and play an important role in modelling realistic galaxies. However, the mechanism that drives these winds remains poorly understood. Cosmic rays provide one possibility to launch the outflows. To improve our understanding of cosmic ray driven winds, I use a set of hydrodynamic simulations of isolated galaxies to study how the wind properties change with halo mass.

Disk Fragmentation as a Planet Formation Scenario
Hans Baehr (MPIA)
ITA "blackboard" Colloquium ( Hephysto link )
Philosophenweg 12, 106
Show/hide abstract

Abstract
Circumstellar disks are likely gravitationally unstable early in their lifetimes when massive and still accreting from their surrounding envelopes. These gravitational instabilities will form spirals and possibly fragment into dense clumps of gas which may result in gas giant planets and low-mass stars. My research uses hydrodynamic simulations to focus on what disk conditions result in the formation of planets and do so over various resolutions to ensure convergence.
