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…
The S stars' zone of avoidance in the Galactic center
Aleksey Generozov, Hagai B. Perets, Matteo S. Bordoni +9
This paper investigates the origin and orbital evolution of S stars in the Galactic center using models of binary disruption and relaxation processes. We focus on explaining the re…
Observations of Microlensed Images with Dual-field Interferometry: On-sky Demonstration and Prospects
P. Mroz, S. Dong, A. Merand +57
Interferometric observations of gravitational microlensing events offer an opportunity for precise, efficient, and direct mass and distance measurements of lensing objects, especia…
First Resolution of Microlensed Images of a Binary-Lens Event
Zexuan Wu, Subo Dong, A. Mérand +72
We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves sh…
