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…
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…
Combining Hipparcos and Gaia data for the study of binaries: the BINARYS tool
A. Leclerc, C. Babusiaux, F. Arenou +6
Orbital motion in binary and planetary systems is the main source of precise stellar and planetary mass measurements, and joint analysis of data from multiple observational methods…
Updated orbital monitoring and dynamical masses for nearby M-dwarf binaries
Per Calissendorff, Markus Janson, Laetitia Rodet +26
Young M-type binaries are particularly useful for precise isochronal dating by taking advantage of their extended pre-main sequence evolution. Orbital monitoring of these low-mass…
ALMA study of the HD 100453 AB system and the tidal interaction of the companion with the disk
G. van der Plas, F. Ménard, J. -F. Gonzalez +6
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 to test spiral for…
SPHERE dynamical and spectroscopic characterization of HD142527B
R. Claudi, A. -L. Maire, D. Mesa +50
We detect the accreting low-mass companion HD142527B at a separation of 73 mas (11.4 au) from the star. No other companions with mass greater than 10 MJ are visible in the field of…
Dynamical masses of M-dwarf binaries in young moving groups: II - Toward empirical mass-luminosity isochrones
Markus Janson, Stephen Durkan, Mickael Bonnefoy +6
Low-mass stars exhibit substantial pre-main sequence evolution during the first ~100 Myrs of their lives. Thus, young M-type stars are prime targets for isochronal dating, especial…
Mapping of shadows cast on a protoplanetary disk by a close binary system
V. D'Orazi, R. Gratton, S. Desidera +47
For a comprehensive understanding of planetary formation and evolution, we need to investigate the environment in which planets form: circumstellar disks. Here we present high-cont…
Dynamical masses of M-dwarf binaries in young moving groups: I - The case of TWA 22 and GJ 2060
L. Rodet, M. Bonnefoy, S. Durkan +48
Evolutionary models are widely used to infer the mass of stars, brown dwarfs, and giant planets. Their predictions are thought to be less reliable at young ages ( 200 Myr) and i…
In-depth study of moderately young but extremely red, very dusty substellar companion HD206893B
P. Delorme, T. Schmidt, M. Bonnefoy +47
The substellar companion HD206893b has recently been discovered by direct imaging of its disc-bearing host star with the SPHERE instrument. We investigate the atypical properties o…
