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…

Multiple Star Systems in the Orion Nebula

GRAVITY collaboration, Martina Karl, Oliver Pfuhl +133

This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium Cluster with the recently comissioned GRAVITY instrument. We observe a total of 16…

GRAVITY chromatic imaging of Eta Car's core

GRAVITY Collaboration, J. Sanchez-Bermudez, G. Weigelt +132

Eta Car is one of the most intriguing luminous blue variables in the Galaxy. Observations and models at different wavelengths suggest a central binary with a 5.54 yr period residin…

Detection of the gravitational redshift in the orbit of the star S2 near the Galactic centre massive black hole

GRAVITY Collaboration, R. Abuter, A. Amorim +95

The highly elliptical, 16-year-period orbit of the star S2 around the massive black hole candidate Sgr A* is a sensitive probe of the gravitational field in the Galactic centre. Ne…
