A first look at the protoplanet WISPIT 2 b with VLTI/GRAVITY+

GRAVITY+ Collaboration, K. Abd El Dayem, R. Abuter +116

Confirmed observations of young protoplanets actively undergoing the process of formation have remained rare to date. In this Letter, we present new insights into the nature of the…

Searching for Nearby Supermassive Black Hole Binaries with GRAVITY

GRAVITY Collaboration, K. Abd El Dayem, N. Aimar +82

We present a systematic interferometric search for close supermassive black hole (SMBH) binaries in 20 nearby type 1 active galactic nuclei (AGN) observed with VLTI/\grav. We inves…

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…

Southern Massive Stars at High Angular Resolution (SMaSH+): Properties of hierarchical massive triples

E. Bordier, H. Sana, A. J. Frost +9

While massive stars are frequently found in triple architectures, the lack of observed parameter distributions has long remained a bottleneck for statistical models of their evolut…

Multi-epoch scattered-light analysis of HD 135344B: new evidence for a spiral-driving protoplanet

J. Latour, V. Christiaens, O. Absil +17

The HD 135344B (SAO 206462) disk exhibits strong signposts of planet formation. ALMA images in the sub-mm revealed a gap-crossing dust filament whose position coincides with a twis…

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…
