A tunnel and a traffic jam: How transition disks maintain a detectable warm dust component despite the presence of a large planet-carved gap
Paola Pinilla, Lucia Klarmann, Tilman Birnstiel +3
We combined hydrodynamical simulations of planet-disk interactions with dust evolution models that include coagulation and fragmentation of dust grains over a large range of radii…
Model atmospheres of irradiated exoplanets: The influence of stellar parameters, metallicity, and the C/O ratio
Paul Mollière, Roy van Boekel, Cornelis Petrus Dullemond +2
Many parameters constraining the spectral appearance of exoplanets are still poorly understood. We therefore study the properties of irradiated exoplanet atmospheres over a wide pa…
Scattered light images of spiral arms in marginally gravitationally unstable discs with an embedded planet
A. Pohl, P. Pinilla, M. Benisty +5
Scattered light images of transition discs in the near-infrared often show non-axisymmetric structures in the form of wide-open spiral arms in addition to their characteristic low-…
Grain size constraints on HL Tau with polarization signature
Akimasa Kataoka, Takayuki Muto, Munetake Momose +2
The millimeter-wave polarization of the protoplanetary disk around HL Tau has been interpreted as the emission from elongated dust grains aligned with the magnetic field in the dis…
Millimeter-wave polarization of protoplanetary disks due to dust scattering
Akimasa Kataoka, Takayuki Muto, Munetake Momose +6
We present a new method to constrain the grain size in protoplanetary disks with polarization observations at millimeter wavelengths. If dust grains are grown to the size comparabl…
The Impact of Dust Evolution and Photoevaporation on Disk Dispersal
Uma Gorti, David Hollenbach, Cornelis Dullemond
Protoplanetary disks are dispersed by viscous evolution and photoevaporation in a few million years; in the interim small, sub-micron sized dust grains must grow and form planets.…
Forming chondrules in impact splashes. I. Radiative cooling model
Cornelis Petrus Dullemond, Sebastian Markus Stammler, Anders Johansen
The formation of chondrules is one of the oldest unsolved mysteries in meteoritics and planet formation. Recently an old idea has been revived: the idea that chondrules form as a r…
