The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits

GRAVITY Collaboration, R. Abuter, N. Aimar +62

The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…

Deep Images of the Galactic Center with GRAVITY

GRAVITY Collaboration, R. Abuter, N. Aimar +65

Stellar orbits at the Galactic Center provide a very clean probe of the gravitational potential of the supermassive black hole. They can be studied with unique precision, beyond th…

Probing inner and outer disk misalignments in transition disks

A. J. Bohn, M. Benisty, K. Perraut +16

For several transition disks (TDs), dark regions interpreted as shadows have been observed in scattered light imaging and are hypothesized to originate from misalignments between d…

The GRAVITY Young Stellar Object survey. VII. The inner dusty disks of T Tauri stars

The GRAVITY Collaboration, K. Perraut, L. Labadie +55

These protoplanetary disks in T Tauri stars play a central role in star and planet formation. We spatially resolve at sub-au scales the innermost regions of a sample of T Tauri's d…

The mass of Beta Pictoris c from Beta Pictoris b orbital motion

S. Lacour, J. J. Wang, L. Rodet +96

We aim to demonstrate that the presence and mass of an exoplanet can now be effectively derived from the astrometry of another exoplanet. We combined previous astrometry of Pic…

A geometric distance to the supermassive black Hole of NGC 3783

GRAVITY Collaboration, A. Amorim, M. Bauböck +45

The angular size of the broad line region (BLR) of the nearby active galactic nucleus (AGN) NGC 3783 has been spatially resolved by recent observations with VLTI/GRAVITY. A reverbe…
