Multi-chromatic observations of classical Cepheids using the CHARA Array interferometer: Surface brightness-colour relation, projection factor, and limb-darkening

M. C. Bailleul, N. Nardetto, D. Mourard +28

The Baade-Wesselink (BW) method compares the linear and angular variations of Cepheids to derive their distance. This method is limited, however, by the projection factor, which re…

Interferometric Survey of Stellar Parameters: Mass of the metallic A-type binary Aur

J. Jonák, D. Mourard, J. D. Monnier +23

With the capabilities of the new visible CHARA/SPICA instrument and the multiple spectral band operation of CHARA, our goal is to resolve orbits of short-period binaries and develo…

Interferometric Survey of Stellar Parameters: Towards homogeneous FGK stars parameters and surface-brightness color relation in the context of PLATO space mission

Romina V. Ibañez Bustos, Denis Mourard, Nicolas Nardetto +20

The estimation of stellar angular diameters can be performed from the surface brightness - color relation (SBCR) and photometry. The SBCR have been considered by the PLATO space mi…

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…

Magnetic field measurements in a sample of Class I and flat-spectrum protostars observed with SPIRou

L. Drouglazet, E. Alecian, A. Sousa +27

Magnetic fields play a crucial role throughout stellar evolution, regulating angular momentum, channelling accretion, and launching jets and outflows. While the magnetic properties…

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 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…

Star-disk interactions in the strongly accreting T Tauri Star S CrA N

H. Nowacki, E. Alecian, K. Perraut +11

Aims : We aimed at constraining the accretion-ejection phenomena around the strongly-accreting Northern component of the S CrA young binary system (S CrA N) by deriving its magneti…
