A family portrait of disk inner rims around Herbig Ae/Be stars: Hunting for warps, rings, self shadowing, and misalignments in the inner astronomical units

J. Kluska, J. -P. Berger, F. Malbet +25

The innermost astronomical unit in protoplanetary disks is a key region for stellar and planet formation, as exoplanet searches have shown a large occurrence of close-in planets th…

The GRAVITY young stellar object survey. II. First spatially resolved observations of the CO bandhead emission in a high-mass YSO

GRAVITY Collaboration, A. Caratti o Garatti, R. Fedriani +50

The inner regions of the discs of high-mass young stellar objects (HMYSOs) are still poorly known due to the small angular scales and the high visual extinction involved. We deploy…

The GRAVITY Young Stellar Object survey -- I. Probing the disks of Herbig Ae/Be stars in terrestrial orbits

K. Perraut, L. Labadie, B. Lazareff +69

The formation and the evolution of protoplanetary disks are important stages in the lifetime of stars. The processes of disk evolution and planet formation are intrinsically linked…

Multiple Star Systems in the Orion Nebula

GRAVITY collaboration, Martina Karl, Oliver Pfuhl +133

This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium Cluster with the recently comissioned GRAVITY instrument. We observe a total of 16…

GRAVITY chromatic imaging of Eta Car's core

GRAVITY Collaboration, J. Sanchez-Bermudez, G. Weigelt +132

Eta Car is one of the most intriguing luminous blue variables in the Galaxy. Observations and models at different wavelengths suggest a central binary with a 5.54 yr period residin…

The wind and the magnetospheric accretion onto the T Tauri star S Coronae Australis at sub-au resolution

R. Garcia Lopez, K. Perraut, A. Caratti o Garatti +70

To investigate the inner regions of protoplanetary disks, we performed near-infrared interferometric observations of the classical TTauri binary system S CrA. We present the first…
