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…

An image of the dust sublimation region in the nucleus of NGC 1068

GRAVITY Collaboration, O. Pfuhl, R. Davies +40

We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…

The GRAVITY Young Stellar Object survey -- I. Probing the disks of Herbig Ae/Be stars in terrestrial orbits

K. Perraut, L. Labadie, B. Lazareff +69

The formation and the evolution of protoplanetary disks are important stages in the lifetime of stars. The processes of disk evolution and planet formation are intrinsically linked…

First direct detection of an exoplanet by optical interferometry; Astrometry and K-band spectroscopy of HR8799 e

S. Lacour, M. Nowak, J. Wang +85

To date, infrared interferometry at best achieved contrast ratios of a few times on bright targets. GRAVITY, with its dual-field mode, is now capable of high contrast obs…
