Meridional Circulation driven by Planetary Spiral Wakes in Radiative and Magnetized Protoplanetary Discs
Marco Cilibrasi, Mario Flock, Judit Szulágyi
We study a Jupiter-mass planet formation for the first time in radiative magneto-hydrodynamics (MHD) simulations and compare it with pure hydrodynamical simulations, as well as to…
Searching for H-emitting sources in the gaps of five transitional disks. SPHERE/ZIMPOL high-contrast imaging
N. Huélamo, G. Chauvin, I. Mendigutía +13
(Pre-)transitional disks show gaps and cavities that can be related with on-going planet formation. According to theory, young embedded planets can accrete material from the circum…
Perturbers: SPHERE detection limits to planetary-mass companions in protoplanetary disks
R. Asensio-Torres, Th. Henning, F. Cantalloube +25
The detection of a wide range of substructures such as rings, cavities and spirals has become a common outcome of high spatial resolution imaging of protoplanetary disks, both in t…
Meridional Circulation of Dust and Gas in the Circumstellar Disk: Delivery of Solids onto the Circumplanetary Region
J. Szulágyi, F. Binkert, C. Surville
We carried out 3D dust+gas radiative hydrodynamic simulations of forming planets. We investigated a parameter grid of Neptune-, Saturn-, Jupiter-, and 5 Jupiter-mass planets at 5.2…
Gap, shadows, spirals, streamers: SPHERE observations of binary-disk interactions in GG Tau A
M. Keppler, A. Penzlin, M. Benisty +31
A large fraction of stars is found to be part of binary or higher-order multiple systems. The ubiquity of planets found around single stars raises the question if and how planets i…
Searching for the near infrared counterpart of Proxima c using multi-epoch high contrast SPHERE data at VLT
R. Gratton, A. Zurlo, H. Le Coroller +43
Proxima Centauri is known to host an earth-like planet in its habitable zone; very recently a second candidate planet was proposed based on radial velocities. At quadrature, the ex…
Hydrogen recombination line luminosities and -variability from forming planets
J. Szulágyi, B. Ercolano
We calculated hydrogen recombination line luminosities (H-, Paschen- and Brackett-) from three dimensional thermo-hydrodynamical simulations of forming planets from 1 to 1…
Can chondrules be produced by the interaction of Jupiter with the protosolar disk?
Jean-David Bodénan, Clément Surville, Judit Szulágyi +2
Chondrules are crystallised droplets of silicates formed by rapid heating to high temperatures (> 1800 K) of solid precursors followed by hours or days of cooling. Dating of chondr…
Formation of satellites in circumplanetary discs generated by disc instability
C. Inderbitzi, J. Szulágyi, M. Cilibrasi +1
We investigated the formation and evolution of satellite systems in a cold, extended circumplanetary disc around a 10 gas giant which was formed by gravitational…
RefPlanets: Search for reflected light from extra-solar planets with SPHERE/ZIMPOL
S. Hunziker, H. M. Schmid, D. Mouillet +55
RefPlanets is a guaranteed time observation (GTO) programme that uses the Zurich IMaging POLarimeter (ZIMPOL) of SPHERE/VLT for a blind search for exoplanets in wavelengths from 60…
Detection of H emission from PZ Tel B using SPHERE/ZIMPOL
Arianna Musso Barcucci, Gabriele Cugno, Ralf Launhardt +7
H is a powerful tracer of accretion and chromospheric activity, which has been detected in the case of young brown dwarfs and even recently in planetary mass companions (e.g. PD…
Dust production in the debris disk around HR 4796 A
J. Olofsson, J. Milli, P. Thébault +21
Debris disks are the natural by-products of the planet formation process. Scattered or polarized light observations are mostly sensitive to small dust grains that are released from…
ALMA observations require slower Core Accretion runaway growth
S. Nayakshin, G. Dipierro, J. Szulagyi
Thanks to recent high resolution ALMA observations, there is an accumulating evidence for presence of giant planets with masses from Jupiter mass to a few Jupiter mass…
Observability of Forming Planets and their Circumplanetary Disks II. -- SEDs and Near-Infrared Fluxes
J. Szulágyi, C. P. Dullemond, A. Pohl +1
Detection of forming planets means detection of the circumplanetary disk (CPD) in reality, since the planet is still surrounded by a disk at this evolutionary stage. Yet, no compre…
Masses and Distances of Planetary Microlens Systems with High Angular Resolution Imaging
Aparna Bhattacharya, Rachel Akeson, Jay Anderson +33
Microlensing is the only method that can detect and measure mass of wide orbit, low mass, solar system analog exoplanets. Mass measurements of such planets would yield massive scie…
