Improving constraints on the extended mass distribution in the Galactic Center with stellar orbits
The GRAVITY Collaboration, Karim Abd El Dayem, Roberto Abuter +66
Studying the orbital motion of stars around Sagittarius A* in the Galactic Center provides a unique opportunity to probe the gravitational potential near the supermassive black hol…
Astrometric detection of a Neptune-mass candidate planet in the nearest M-dwarf binary system GJ65 with VLTI/GRAVITY
GRAVITY Collaboration, R. Abuter, A. Amorim +65
The detection of low-mass planets orbiting the nearest stars is a central stake of exoplanetary science, as they can be directly characterized much more easily than their distant c…
VLTI/GRAVITY Observations and Characterization of the Brown Dwarf Companion HD 72946 B
W. O. Balmer, L. Pueyo, T. Stolker +96
Tension remains between the observed and modeled properties of substellar objects, but objects in binary orbits, with known dynamical masses can provide a way forward. HD 72946 B i…
Polarimetry and Astrometry of NIR Flares as Event Horizon Scale, Dynamical Probes for the Mass of Sgr A*
The GRAVITY Collaboration, R. Abuter, N. Aimar +66
We present new astrometric and polarimetric observations of flares from Sgr A* obtained with GRAVITY, the near-infrared interferometer at ESO's Very Large Telescope Interferometer…
Using the motion of S2 to constrain scalar clouds around SgrA*
GRAVITY Collaboration, A. Foschi, R. Abuter +67
The motion of S2, one of the stars closest to the Galactic Centre, has been measured accurately and used to study the compact object at the centre of the Milky Way. It is commonly…
Where intermediate-mass black holes could hide in the Galactic Centre: A full parameter study with the S2 orbit
The GRAVITY Collaboration, O. Straub, M. Bauböck +59
In the Milky Way the central massive black hole, SgrA*, coexists with a compact nuclear star cluster that contains a sub-parsec concentration of fast-moving young stars called S-st…
