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…

NAOMI: the adaptive optics system of the Auxiliary Telescopes of the VLTI

Woillez J., Abad J. A., Abuter R. +80

The tip-tilt stabilisation system of the 1.8 m Auxiliary Telescopes of the Very Large Telescope Interferometer was never dimensioned for robust fringe tracking, except when atmosph…

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…

The GRAVITY fringe tracker

S. Lacour, R. Dembet, R. Abuter +17

The GRAVITY instrument has been commissioned on the VLTI during 2016 and is now available to the astronomical community. It is the first optical interferometer capable of observing…
