The GRAVITY young stellar object survey -- XV. The star-disk interaction region of the T Tauri star DO Tau
GRAVITY Collaboration, K. Perraut, J. Bouvier +61
Protoplanetary disks around young Sun-like stars are the cradles of the vast majority of detected exoplanets. Probing these disks at multiple spatial scales is key to uncovering ho…
The GRAVITY young stellar object survey XIV : Investigating the magnetospheric accretion-ejection processes in S CrA N
GRAVITY Collaboration, H. Nowacki, K. Perraut +53
The dust- and gas-rich protoplanetary disks around young stellar systems play a key role in star and planet formation. While considerable progress has recently been made in probing…
A new dimension in the variability of AGB stars: convection patterns size changes with pulsation
A. Rosales-Guzmán, J. Sanchez-Bermudez, C. Paladini +16
Stellar convection plays an important role in atmospheric dynamics, wind formation and the mass-loss processes in Asymptotic Giant Branch (AGB) stars. However, a direct characteriz…
The GRAVITY young stellar object survey XIII. Tracing the time-variable asymmetric disk structure in the inner AU of the Herbig star HD98922
GRAVITY Collaboration, V. Ganci, L. Labadie +52
Temporal variability in the photometric and spectroscopic properties of protoplanetary disks is common in YSO. However, evidence pointing toward changes in their morphology over sh…
VLTI/GRAVITY Provides Evidence the Young, Substellar Companion HD 136164 Ab formed like a "Failed Star"
William O. Balmer, L. Pueyo, S. Lacour +93
Young, low-mass Brown Dwarfs orbiting early-type stars, with low mass ratios (), appear intrinsically rare and present a formation dilemma: could a handful of these…
The GRAVITY Young Stellar Object survey. VII. The inner dusty disks of T Tauri stars
The GRAVITY Collaboration, K. Perraut, L. Labadie +55
These protoplanetary disks in T Tauri stars play a central role in star and planet formation. We spatially resolve at sub-au scales the innermost regions of a sample of T Tauri's d…
The GRAVITY young stellar object survey V. The orbit of the T Tauri binary star WW Cha
GRAVITY Collaboration, F. Eupen, L. Labadie +60
The young T Tauri star WW Cha was recently proposed to be a close binary object with strong infrared and submillimeter excess associated with circum-system emission. This makes WW…
Probing the magnetospheric accretion region of the young pre-transitional disk system DoAr 44 using VLTI/GRAVITY
J. Bouvier, K. Perraut, J. -B. Le Bouquin +6
Young stellar objects are thought to accrete material from their circumstellar disks through their strong stellar magnetospheres. We aim to directly probe the magnetospheric accret…
Resolved astrometric orbits of ten O-type binaries
J. -B. Le Bouquin, H. Sana, E. Gosset +11
Our long term aim is to derive model-independent stellar masses and distances for long period massive binaries by combining apparent astrometric orbit with double-lined radial velo…
Strong near-infrared emission in the sub-AU disk of the Herbig Ae star HD163296: evidence for refractory dust?
M. Benisty, A. Natta, A. Isella +12
We present new long-baseline spectro-interferometric observations of the HerbigAe star HD163296 obtained in the H and K bands with the AMBER instrument at VLTI. The observations co…
