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…
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…
A near-infrared interferometric survey of debris disc stars. II. CHARA/FLUOR observations of six early-type dwarfs
O. Absil, E. Di Folco, A. Merand +15
High-precision interferometric observations of six early-type main sequence stars known to harbour cold debris discs have been obtained in the near-infrared K band with the FLUOR i…
A catalog of bright calibrator stars for 200-meter baseline near-infrared stellar interferometry
A. Merand, P. Borde, V. Coude du Foresto
We present in this paper a catalog of reference stars suitable for calibrating infrared interferometric observations. In the K band, visibilities can be calibrated with a precision…
