Imaging the expanding knotty structure in the close environment of the LBV star Carinae

F. Millour, E. Lagadec, M. Montargès +13

~Car is one of the most massive stars in the Galaxy. It underwent a massive eruption in the 19th century, which produced the impressive bipolar Homunculus nebula now surrounding…

K-Stacker, an algorithm to hack the orbital parameters of planets hidden in high-contrast imaging. First applications to VLT SPHERE multi-epoch observations

H. Le Coroller, M. Nowak, P. Delorme +40

Recent high-contrast imaging surveys, looking for planets in young, nearby systems showed evidence of a small number of giant planets at relatively large separation beyond typicall…

The polarimetric imaging mode of VLT/SPHERE/IRDIS II: Characterization and correction of instrumental polarization effects

R. G. van Holstein, J. H. Girard, J. de Boer +31

Context. Circumstellar disks and self-luminous giant exoplanets or companion brown dwarfs can be characterized through direct-imaging polarimetry at near-infrared wavelengths. SPHE…

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…

Detection of the gravitational redshift in the orbit of the star S2 near the Galactic centre massive black hole

GRAVITY Collaboration, R. Abuter, A. Amorim +95

The highly elliptical, 16-year-period orbit of the star S2 around the massive black hole candidate Sgr A* is a sensitive probe of the gravitational field in the Galactic centre. Ne…
