Substellar Initial Mass Function of Trumpler 14
Tamara Rom, Estelle Moraux, Koraljka Mužić +3
Young, massive stellar clusters offer a prime setting to explore brown dwarf (BD) formation under high densities and intense UV radiation. Trumpler 14 (Tr 14), a 1 Myr-old cluster…
VLTI/GRAVITY Observations and Characterization of the Brown Dwarf Companion HD 72946 B
W. O. Balmer, L. Pueyo, T. Stolker +96
Tension remains between the observed and modeled properties of substellar objects, but objects in binary orbits, with known dynamical masses can provide a way forward. HD 72946 B i…
The HD 98800 quadruple pre-main sequence system. Towards full orbital characterisation using long-baseline infrared interferometry
S. Zúñiga-Fernández, J. Olofsson, A. Bayo +8
HD 98800 is a young ( Myr old) and nearby ( pc) quadruple system, composed of two spectroscopic binaries orbiting around each other (AaAb and BaBb), with a gas-rich…
A MUSE Spectro-imaging Study of the Th 28 Jet: Precession in the Inner Jet
A. Murphy, C. Dougados, E. T. Whelan +5
Context: Th 28 is a Classical T Tauri star in the Lupus 3 cloud which drives an extended bipolar jet. Previous studies of the inner jet identified signatures of rotation around the…
A measure of the size of the magnetospheric accretion region in TW Hydrae
R. Garcia Lopez, A. Natta, A. Caratti o Garatti +69
Stars form by accreting material from their surrounding disks. There is a consensus that matter flowing through the disk is channelled onto the stellar surface by the stellar magne…
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…
The GRAVITY young stellar object survey. II. First spatially resolved observations of the CO bandhead emission in a high-mass YSO
GRAVITY Collaboration, A. Caratti o Garatti, R. Fedriani +50
The inner regions of the discs of high-mass young stellar objects (HMYSOs) are still poorly known due to the small angular scales and the high visual extinction involved. We deploy…
The lithium-rotation connection in the newly discovered young stellar stream Psc-Eri (Meingast 1)
J. Arancibia-Silva, J. Bouvier, A. Bayo +4
Context. As a fragile element, lithium is a sensitive probe of physical processes occurring in stellar interiors. Aims. We aim at investigating the relationship between lithium abu…
Dense cores and star formation in the giant molecular cloud Vela~C
F. Massi, A. Weiss, D. Elia +12
Context The Vela Molecular Ridge is one of the nearest (700 pc) giant molecular cloud (GMC) complexes hosting intermediate-mass (up to early B, late O stars) star formation, and is…
Is stellar multiplicity universal? Tight stellar binaries in the Orion Nebula Cluster
Gaspard Duchene, Sylvestre Lacour, Estelle Moraux +2
We present a survey for the tightest visual binaries among 0.3-2 Msun members the Orion Nebula Cluster (ONC). Among 42 targets, we discovered 13 new 0.025-0.15" companions. Account…
The wind and the magnetospheric accretion onto the T Tauri star S Coronae Australis at sub-au resolution
R. Garcia Lopez, K. Perraut, A. Caratti o Garatti +70
To investigate the inner regions of protoplanetary disks, we performed near-infrared interferometric observations of the classical TTauri binary system S CrA. We present the first…
Decrease of the organic deuteration during the evolution of Sun-like protostars: the case of SVS13-A
E. Bianchi, C. Codella, C. Ceccarelli +6
We present the results of formaldehyde and methanol deuteration measurements towards the Class I low-mass protostar SVS13-A, in the framework of the IRAM 30-m ASAI (Astrochemical S…
