Improving constraints on the Yukawa correction at the Galactic Center with multiple stellar orbits
GRAVITY+ Collaboration, :, A. Foschi +78
We investigate the presence of a Yukawa-like correction () to Newtonian gravity at the Galactic Center, using a multi-star fitting code, including the newly…
Discovery of a star sensitive to the spin of Sgr A*
K. Abd El Dayem, R. Abuter, N. Aimar +85
Residing in the center of the Milky Way, Sgr A* is the closest massive black hole (MBH). Its vicinity has allowed measuring individual stellar orbits around it. The stars act as te…
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…
Using the motion of S2 to constrain vector clouds around SgrA*
GRAVITY Collaboration, A. Foschi, R. Abuter +53
The dark compact object at the centre of the Milky Way is well established to be a supermassive black hole with mass , but the nature…
Polarization analysis of the VLTI and GRAVITY
GRAVITY Collaboration, F. Widmann, X. Haubois N. Schuhler +59
The goal of this work is to characterize the polarization effects of the VLTI and GRAVITY. This is needed to calibrate polarimetric observations with GRAVITY for instrumental effec…
First VLTI/GRAVITY Observations of HIP 65426 b: Evidence for a Low or Moderate Orbital Eccentricity
S. Blunt, W. O. Balmer, J. J. Wang +95
Giant exoplanets have been directly imaged over orders of magnitude of orbital separations, prompting theoretical and observational investigations of their formation pathways. In t…
