Effects of a disk structure on stellar motion at the Galactic Center
Arianna Foschi, Frederic H. Vincent, Thibaut Paumard +1
The paper investigates how a thin, disk-like mass distribution around the Milky Way’s central black hole influences the orbits of nearby stars such as S2 and S301, providing analyt…
Discovery of a star sensitive to the spin of Sgr A*
K. Abd El Dayem, R. Abuter, N. Aimar +85
The paper reports the discovery of a faint main‑sequence star (S301) on an 8.7‑year, highly eccentric orbit around the Milky Way’s central black hole, whose high velocity makes its…
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…
Exploring the presence of a fifth force at the Galactic Center
The GRAVITY Collaboration, K. Abd El Dayem, R. Abuter +60
Aims: The presence of a Yukawa-like correction to Newtonian gravity is investigated at the Galactic Center, leading to a new upper limit for the intensity of such a correction. Met…
Spatially resolved broad line region in a quasar at z=4: Dynamical black hole mass and prominent outflow
GRAVITY+ Collaboration, K. Abd El Dayem, N. Aimar +92
We present the first near-infrared interferometric data of a QSO at z=4. The K-band observations were performed with GRAVITY+ on the VLTI using all four UTs, detecting a differenti…
Exomoon search with VLTI/GRAVITY around the substellar companion HD 206893 B
Q. Kral, J. Wang, J. Kammerer +130
Direct astrometric detection of exomoons remains unexplored. This study presents the first application of high-precision astrometry to search for exomoons around substellar compani…
