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…

The Orbital Structure and Selection Effects of the Galactic Center S-Star Cluster

Andreas Burkert, Stefan Gillessen, Douglas N. C. Lin +4

The orbital distribution of the S-star cluster surrounding the supermassive black hole in the center of the Milky Way is analyzed. A tight, roughly exponential dependence of the pe…

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…
