Ionized envelopes around protoplanets and the role of radiative feedback in gas accretion
Matías Montesinos, Juan Garrido-Deutelmoser, Jorge Cuadra +5
Planetary growth within protoplanetary disks involves accreting material from their surroundings, yet the underlying mechanisms and physical conditions of the accreting gas remain…
The missing rings around Solar System moons
Mario Sucerquia, Jaime A. Alvarado-Montes, Jorge I. Zuluaga +3
Rings are complex structures surrounding giant planets and some minor bodies in the Solar System. While some formation mechanisms could also potentially foster their existence arou…
Morphology of the gas-rich debris disk around HD 121617 with SPHERE observations in polarized light
Clément Perrot, Johan Olofsson, Quentin Kral +7
Debris disks are the signposts of collisionally eroding planetesimal circumstellar belts, whose study can put important constraints on the structure of extrasolar planetary systems…
The vertical structure of debris disks and the impact of gas
Johan Olofsson, Philippe Thébault, Quentin Kral +10
The vertical structure of debris disks provides clues about their dynamical evolution and the collision rate of the unseen planetesimals. Thanks to the ever-increasing angular reso…
The protoplanetary disc around HD 169142: circumstellar or circumbinary?
P. P. Poblete, N. Cuello, S. Pérez +12
Stellar binaries represent a substantial fraction of stellar systems, especially among young stellar objects. Accordingly, binaries play an important role in setting the architectu…
Cronomoons: origin, dynamics, and light-curve features of ringed exomoons
Mario Sucerquia, Jaime A. Alvarado-Montes, Amelia Bayo +8
In recent years, technical and theoretical work to detect moons and rings around exoplanets has been attempted. The small mass/size ratios between moons and planets means this is v…
Radiative scale-height and shadows in protoplanetary disks
Matías Montesinos, Nicolás Cuello, Johan Olofsson +4
Planets form in young circumstellar disks called protoplanetary disks. However, it is still difficult to catch planet formation in-situ. Nevertheless, from recent ALMA/SPHERE data,…
Dust trapping around Lagrangian points in protoplanetary disks
Matias Montesinos, Juan Garrido-Deutelmoser, Johan Olofsson +5
Trojans are defined as objects that share the orbit of a planet at the stable Lagrangian points and . In the Solar System, these bodies show a broad size distribution ra…
On moving shadows and pressure bumps in HD 169142
Gesa H. -M. Bertrang, Mario Flock, Miriam Keppler +5
The search for young planets had its first breakthrough with the detection of the accreting planet PDS70b. In this study, we aim to broaden our understanding towards the formation…
Scattered light may reveal the existence of ringed exoplanets
Mario Sucerquia, Jaime A. Alvarado-Montes, Jorge I. Zuluaga +2
Rings around giant exoplanets (hereafter 'exorings') are still a missing planetary phenomenon among the vast number of discovered planets. Despite the fact there exist a large numb…
The widest H survey of accreting protoplanets around nearby transition disks
A. Zurlo, G. Cugno, M. Montesinos +6
The mechanisms of planet formation are still under debate. We know little about how planets form, even if more than 4000 exoplanets have been detected to date. Recent investigation…
NaCo polarimetric observations of Sz 91 transitional disk: a remarkable case of dust filtering
Karina Maucó, Johan Olofsson, Hector Canovas +10
We present polarized light observations of the transitional disk around Sz 91 acquired with VLT/NaCo at (1.7m) and (2.2m) bands. We resolve the disk and detect pola…
Flybys in protoplanetary discs: II. Observational signatures
Nicolás Cuello, Fabien Louvet, Daniel Mentiplay +14
Tidal encounters in star clusters perturb discs around young protostars. In Cuello et al. (2019a, Paper I) we detailed the dynamical signatures of a stellar flyby in both gas and d…
An unusually large gaseous transit in a debris disc
Daniela P. Iglesias, Johan Olofsson, Amelia Bayo +9
We present the detection of an unusually large transient gas absorption in several ionized species in the debris disc star HD 37306 using high-resolution optical spectra. We have b…
Evidence for a circumplanetary disk around protoplanet PDS 70 b
V. Christiaens, F. Cantalloube, S. Casassus +5
We present the first observational evidence for a circumplanetary disk around the protoplanet PDS~70~b, based on a new spectrum in the band acquired with VLT/SINFONI. We tested…
Thermal torque effects on the migration of growing low-mass planets
O. M. Guilera, N. Cuello, M. Montesinos +4
As planets grow the exchange of angular momentum with the gaseous component of the protoplanetary disc produces a net torque resulting in a variation of the semi-major axis of the…
Flybys in protoplanetary discs: I. Gas and dust dynamics
Nicolás Cuello, Giovanni Dipierro, Daniel Mentiplay +7
We present 3D smoothed particle hydrodynamics simulations of protoplanetary discs undergoing a flyby by a stellar perturber on a parabolic orbit lying in a plane inclined relative…
Dusty spirals triggered by shadows in transition discs
Nicolás Cuello, Matías Montesinos, Sebastian M. Stammler +2
Context. Despite the recent discovery of spiral-shaped features in protoplanetary discs in the near-infrared and millimetric wavelengths, there is still an active discussion to und…
F.S.I.: Flyby Scene Investigation
Nicolás Cuello, Giovanni Dipierro, Daniel Mentiplay +7
We present a methodology to interpret observations of protoplanetary discs where a flyby, also called a tidal encounter, is suspected. In case of a flyby, protoplanetary discs can…
Planetary-like spirals caused by moving shadows in transition discs
Matías Montesinos, Nicolás Cuello
Shadows and spirals seem to be common features of transition discs. Among the spiral-triggering mechanisms proposed, only one establishes a causal link between shadows and spirals…
HD 169142 in the eyes of ZIMPOL/SPHERE
G. H. -M. Bertrang, H. Avenhaus, S. Casassus +5
We present new data of the protoplanetary disc surrounding the Herbig Ae/Be star HD 169142 obtained in the very broad-band (VBB) with the Zurich imaging polarimeter (ZIMPOL), a sub…
Feedback-limited Accretion: Variable Luminosity from Growing Planets
Matías Gárate, Jorge Cuadra, Matias Montesinos +1
Planets form in discs of gas and dust around stars, and continue to grow by accretion of disc material while available. Massive planets clear a gap in their protoplanetary disc, bu…
Spiral waves triggered by shadows in transition disks
Matias Montesinos, Sebastian Perez, Simon Casassus +3
Circumstellar asymmetries such as central warps have recently been shown to cast shadows on outer disks. We investigate the hydrodynamical consequences of such variable illuminatio…
Protoplanetary disks including radiative feedback from accreting planets
Matias Montesinos, Jorge Cuadra, Sebastian Perez +2
While recent observational progress is converging on the detection of compact regions of thermal emission due to embedded protoplanets, further theoretical predictions are needed t…
