Impact splash chondrule formation during planetesimal recycling
Tim Lichtenberg, Gregor J. Golabek, Cornelis P. Dullemond +3
Chondrules are the dominant bulk silicate constituent of chondritic meteorites and originate from highly energetic, local processes during the first million years after the birth o…
Dust-driven viscous ring-instability in protoplanetary disks
C. P. Dullemond, A. B. T. Penzlin
Protoplanetary disks often appear as multiple concentric rings in dust continuum emission maps and scattered light images. These features are often associated with possible young p…
Efficiency of thermal relaxation by radiative processes in protoplanetary discs: constraints on hydrodynamic turbulence
M. G. Malygin, H. Klahr, D. Semenov +2
Hydrodynamic, non-magnetic instabilities can provide turbulent stress in the regions of protoplanetary discs, where the MRI can not develop. The induced motions influence the grain…
Mid-infrared interferometric variability of DG Tau: implications for the inner-disk structure
J. Varga, K. É. Gabányi, P. Ábrahám +12
Context. DG Tau is a low-mass pre-main sequence star, whose strongly accreting protoplanetary disk exhibits a so-far enigmatic behavior: its mid-infrared thermal emission is strong…
Redistribution of CO at the Location of the CO Ice Line in evolving Gas and Dust Disks
Sebastian Markus Stammler, Tilman Birnstiel, Olja Panić +2
Context. Ice lines are suggested to play a significant role in grain growth and planetesimal formation in protoplanetary disks. Evaporation fronts directly influence the gas and ic…
