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…

The cool brown dwarf Gliese 229 B is a close binary

Jerry W. Xuan, A. Mérand, W. Thompson +76

Owing to their similarities with giant exoplanets, brown dwarf companions of stars provide insights into the fundamental processes of planet formation and evolution. From their orb…

Improving constraints on the extended mass distribution in the Galactic Center with stellar orbits

The GRAVITY Collaboration, Karim Abd El Dayem, Roberto Abuter +66

Studying the orbital motion of stars around Sagittarius A* in the Galactic Center provides a unique opportunity to probe the gravitational potential near the supermassive black hol…

The interplay between disk wind and magnetospheric accretion mechanisms in the innermost environment of RU Lup

J. A. Wojtczak, B. Tessore, L. Labadie +10

Aims: Our aim is to build upon the analysis presented in our previous work by attempting to match the observational data obtained with VLTI GRAVITY for RU Lup in 2021 with an expan…

The GRAVITY young stellar object survey XIV : Investigating the magnetospheric accretion-ejection processes in S CrA N

GRAVITY Collaboration, H. Nowacki, K. Perraut +53

The dust- and gas-rich protoplanetary disks around young stellar systems play a key role in star and planet formation. While considerable progress has recently been made in probing…

VLTI/GRAVITY Interferometric Measurements of Innermost Dust Structure Sizes around AGNs

GRAVITY Collaboration, A. Amorim, G. Bourdarot +41

We present new VLTI/GRAVITY near-infrared interferometric measurements of the angular size of the innermost hot dust continuum for 14 type 1 AGNs. The angular sizes are resolved on…
