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…
GRAVITY+: reducing non-common-path aberrations for sub-10 μas astrometric accuracy
Quentin Fournier, Guillaume Bourdarot, Frank Eisenhauer +26
GRAVITY is a state-of-the-art instrument for near-infrared astrometric interferometry that routinely achieves astrometric accuracy of 30-100 microarcsecond in its phase-referenced…
Effects of a disk structure on stellar motion at the Galactic Center
Arianna Foschi, Frederic H. Vincent, Thibaut Paumard +1
Stellar orbits are key for probing the environment of the supermassive black hole at the Galactic Center, Sagittarius A. So far, the mass around SgrA has been assumed to be…
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…
Using VLTI/GRAVITY+ to determine the identity of a third planet candidate in the PDS 70 system
David Trevascus, Wolfgang Brandner, Olga Balsalobre-Ruza +75
Detections of protoplanets are rare and protoplanetary disk features mischaracterized as planets are common. PDS 70 is one of only two stars known to host multiple confirmed protop…
The GRAVITY young stellar object survey -- XV. The star-disk interaction region of the T Tauri star DO Tau
GRAVITY Collaboration, K. Perraut, J. Bouvier +61
Protoplanetary disks around young Sun-like stars are the cradles of the vast majority of detected exoplanets. Probing these disks at multiple spatial scales is key to uncovering ho…
