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 ...

Compact Dust Concentration in the MWC 758 Protoplanetary Disk
(The American Astronomical Society, 2015-11-01)
The formation of planetesimals requires that primordial dust grains grow from micron- to kilometer-sized bodies.
Dust traps caused by gas pressure maxima have been proposed as regions where grains can concentrate and ...
Millimeter spectral indices and dust trapping by planets in brown dwarf disks
(IOP Publishing Ltd, 2017)
Disks around brown dwarfs (BDs) are excellent laboratories to study the first steps of planet formation in cold and low-mass disk conditions. The radial-drift velocities of dust particles in BD disks higher than in disks ...
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 ...
A co survey in planet-forming disks: characterizing the gas content in the epoch of planet formation
(The American Astronomical Society., 2014-07-31)
We carried out a 12CO(3-2) survey of 52 southern stars with a wide range of IR excesses (L IR/L *) using the single-dish telescopes APEX and ASTE. The main aims were (1) to characterize the evolution of molecular gas in ...
Compact dust concentration in the mwc 758 protoplanetary disk
(IOP Publishing, 2015)
The formation of planetesimals requires that primordial dust grains grow from micron- to km-sized bodies.
Dust traps caused by gas pressure maxima have been proposed as regions where grains can concentrate and
grow fast ...
The GRAVITY young stellar object survey: IV. The CO overtone emission in 51 Oph at sub-au scales
(EDP Sciences, 2021)
Context. 51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 mu m, most likely originating in the innermost regions of a circumstellar disc.Aims. We aim to obtain the physical ...
The GRAVITY young stellar object survey VII. The inner dusty disks of T Tauri stars
(EDP Sciences, 2021)
Context. T Tauri stars are surrounded by dust and gas disks. As material reservoirs from which matter is accreted onto the central star
and planets are built, these protoplanetary disks play a central role in star and ...
