A bright inner disk and structures in the transition disk around the very low-mass star CIDA1
(EDP Sciences, 2021)
The frequency of Earth-sized planets in habitable zones appears to be higher around M-dwarfs, making these systems exciting laboratories to investigate planet formation. Observations of protoplanetary disks around very ...
ALMA study of the HD 100453 AB system and the tidal interaction of the companion with the disk
(EDP Sciences, 2019)
Context. The complex system HD 100453 AB with a ring-like circumprimary disk and two spiral arms, one of which is pointing to the secondary, is a good laboratory in which to test spiral formation theories. Aims. We aim to ...
Evidence for a Circumplanetary Disk around Protoplanet PDS 70 b
(Institute of Physics Publishing, 2019)
© 2019. The American Astronomical Society. All rights reserved.We present the first observational evidence for a circumplanetary disk (CPD) around the protoplanet PDS 70 b, based on a new spectrum in the K-band acquired ...
Consequences of the simultaneous formation of giant planets by the core accretion mechanism
(EDP Sciences, 2010-10)
Context. The core accretion mechanism is presently the most widely accepted cause of the formation of giant planets. For simplicity, most models presently assume that the growth of planetary embryos occurs in isolation. ...
Disks around T Tauri Stars with SPHERE (DARTTS-S). I. SPHERE/IRDIS Polarimetric Imaging of Eight Prominent T Tauri Disks
(Institute of Physics Publishing, 2018)
We present the first part of our Disks ARound T Tauri Stars with SPHERE (DARTTS-S) survey: observations of eight T Tauri stars that were selected based on their strong (sub)millimeter excesses using SPHERE/IRDIS polarimetric ...
Disks around T tauri stars with SPHERE (DARTTS-S). I. SPHERE/IRDIS polarimetric imaging of eight prominent T tauri disks
(IOP Publishing, 2018)
We present the first part of our Disks ARound T Tauri Stars with SPHERE (DARTTS-S) survey: observations of eight T Tauri stars that were selected based on their strong (sub)millimeter excesses using SPHERE/IRDIS polarimetric ...
Thermal torque effects on the migration of growing low-mass planets
(Wiley Blackwell Publishing, Inc, 2019-07)
As planets grow the exchange of angular momentum with the gaseous component ofthe protoplanetary disc produces a net torque resulting in a variation of the semi-major axis of the planet. For low-mass planets not able to ...
Long-term and large-scale hydrodynamical simulations of migrating planets
(IOP Publishing, 2016-07)
We present a new method that allows for long-term and large-scale hydrodynamical simulations of migrating planets over a grid-based Eulerian code. This technique, which consists of a remapping of the disk by tracking the ...
The circumstellar disk HD 169142: gas, dust, and planets acting in concert?
(IOP Publishing Ltd., 2017)
HD 169142 is an excellent target for investigating signs of planet-disk interaction due to previous evidence of gap structures. We perform J-band (similar to 1.2 mu m) polarized intensity imaging of HD 169142 with VLT/SPHERE. ...
Nebular gas drag and planetary accretion with eccentric high-mass planets
(2013-04-08)
Aims.We investigate the dynamics of pebbles immersed in a gas disk interacting with a planet on an eccentric orbit. The model has a prescribed gap in the disk around the location of the planetary orbit, as is expected for ...
