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…
Planet Formation Imager: Project Update
John D. Monnier, Michael J. Ireland, Stefan Kraus +2
The Planet Formation Imager (PFI) is a near- and mid-infrared interferometer project with the driving science goal of imaging directly the key stages of planet formation, including…
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…
New evidence for the dusty wind model: Polar dust and a hot core in the type-1 Seyfert ESO323-G77
James Leftley, Konrad Tristram, Sebastian Hönig +3
Infrared interferometry of Seyfert galaxies has revealed that their warm (K) dust emission originates primarily from polar regions instead of from an equatorial dust tor…
Hi-5: a potential high-contrast thermal near-infrared imager for the VLTI
D. Defrère, M. Ireland, O. Absil +25
Hi-5 is a high-contrast (or high dynamic range) infrared imager project for the VLTI. Its main goal is to characterize young extra-solar planetary systems and exozodiacal dust arou…
