Steady-state accretion in magnetized protoplanetary disks
Timmy N. Delage, Satoshi Okuzumi, Mario Flock +2
[abridged] We present a 1+1D global magnetically-driven disk accretion model that captures the essence of the MRI-driven accretion, without resorting to 3D global non-ideal MHD sim…
Midplane temperature and outer edge of the protoplanetary disk around HD 163296
Cornelis Dullemond, Andrea Isella, Sean Andrews +2
Knowledge of the midplane temperature of protoplanetary disks is one of the key ingredients in theories of dust growth and planet formation. However, direct measurement of this qua…
The magnetic diffusivities in 3D radiative chemo-hydrodynamic simulations of protostellar collapse
Natalia Dzyurkevich, Benoit Commercon, Pierre Lesaffre +1
The grand question of star and planet formation is the distribution of magnetic flux in the protoplanetary disks. To answer it, a detailed self-consistent chemical evolution is nee…
3D radiative hydrodynamic simulations of protostellar collapse with H-C-O dynamical chemistry
Natalia Dzyurkevich, Benoît Commerçon, Pierre Lesaffre +1
Combining the co-evolving chemistry, hydrodynamics and radiative transfer is an important step for star formation studies. It allows both a better link to observations and a self-c…
Gaps, rings, and non-axisymmetric structures in protoplanetary disks - Emission from large grains
J. P. Ruge, M. Flock, S. Wolf +5
Dust grains with sizes around (sub)mm are expected to couple only weakly to the gas motion in regions beyond 10 au of circumstellar disks. In this work, we investigate the influenc…
Gaps, Rings, and Non-Axisymmetric Structures in Protoplanetary Disks - From Simulations to ALMA Observations
M. Flock, J. P. Ruge, N. Dzyurkevich +3
Recent observations by the Atacama Large Millimeter/submillimeter Array (ALMA) of disks around young stars revealed distinct asymmetries in the dust continuum emission. In this wor…
Magnetized Accretion and Dead Zones in Protostellar Disks
Natalia Dzyurkevich, Neal J. Turner, Thomas Henning +1
The edges of magnetically-dead zones in protostellar disks have been proposed as locations where density bumps may arise, trapping planetesimals and helping form planets. Magneto-r…
Turbulence and Steady Flows in 3D Global Stratified MHD Simulations of Accretion Disks
M. Flock, N. Dzyurkevich, H. Klahr +2
We present full 2 Pi global 3-D stratified MHD simulations of accretion disks. We interpret our results in the context of proto-planetary disks. We investigate the turbulence drive…
Internal dynamics and membership of the NGC 3603 Young Cluster from microarcsecond astrometry
Boyke Rochau, Wolfgang Brandner, Andrea Stolte +5
We have analyzed two epochs of HST/WFPC2 observations of the young Galactic starburst cluster in NGC 3603 with the aim to study its internal dynamics and stellar population. Relati…
Trapping Solids at the Inner Edge of the Dead Zone: 3-D Global MHD Simulations
Natalia Dzyurkevich, Mario Flock, Neal J. Turner +2
The poorly-ionized interior of the protoplanetary disk is the location where dust coagulation processes may be most efficient. However even here, planetesimal formation may be limi…
