Infrared wavefront sensing for adaptive optics assisted Galactic Center observations with the VLT interferometer and GRAVITY: operation and results

Stefan Hippler, Wolfgang Brandner, Silvia Scheithauer +15

This article describes the operation of the near-infrared wavefront sensing based Adaptive Optics (AO) system CIAO. The Coudé Infrared Adaptive Optics (CIAO) system is a central au…

Peering into the formation history of beta Pictoris b with VLTI/GRAVITY long baseline interferometry

GRAVITY Collaboration, M. Nowak, S. Lacour +65

Our objective is to estimate the C/O ratio in the atmosphere of beta Pictoris b and obtain an estimate of the dynamical mass of the planet, as well as to refine its orbital paramet…

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…

Test of Einstein equivalence principle near the Galactic center supermassive black hole

A. Amorim, M. Bauböck, J. P. Berger +49

During its orbit around the four million solar mass black hole Sagittarius A* the star S2 experiences significant changes in gravitational potential. We use this change of potentia…
