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 GRAVITY Young Stellar Object Survey. VI. Mapping the variable inner disk of HD 163296 at sub-au scales

J. Sanchez-Bermudez, A. Caratti o Garatti, R. Garcia Lopez +53

Protoplanetary disks drive some of the formation process (e.g., accretion, gas dissipation, formation of structures, etc.) of stars and planets. Understanding such physical process…

MOLsphere and pulsations of the Galactic Center's red supergiant GCIRS 7 from VLTI/GRAVITY

GRAVITY Collaboration, G. Rodríguez-Coira, T. Paumard +55

GCIRS 7, the brightest star in the Galactic central parsec, formed Myr ago together with dozens of massive stars in a disk orbiting the central black-hole. It has been argu…

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 IV. The CO overtone emission in 51 Oph at sub-au scales

GRAVITY Collaboration, M. Koutoulaki, R. Garcia Lopez +69

51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 micron, most likely originating in the innermost regions of a circumstellar disc.…

The GRAVITY young stellar object survey III. The dusty disk of RY Lup

GRAVITY Collaboration, Y. -I. Bouarour, K. Perraut +55

We use PIONIER data from the ESO archive and GRAVITY data that were obtained in June 2017 with the four 8m telescopes. We use a parametric disk model and the 3D radiative transfer…
