SPHERE/ZIMPOL observations of the symbiotic system R Aquarii. II. Dynamics of the dust in the Mira wind and the Halpha gas in the jet

H. M. Schmid, E. Lagadec, J. Milli +17

R Aqr is a resolved symbiotic Mira binary and a prototype target for the study of complex hydrodynamic processes including dust-driven mass loss, mass transfer, accretion, and jet…

Cascade adaptive optics with a second stage based on a Zernike wavefront sensor for exoplanet observations II. Validation in broadband light on the ESO/GHOST testbed

A. Rahim, M. N'Diaye, A. Vigan +10

Current high-contrast facilities on the ground use extreme adaptive optics (XAO) systems to achieve contrasts down to at 200\,mas for exoplanet observations. This perform…

Cold and eccentric: a high-spectral resolution view of 51 Eri b with VLT/HiRISE

A. Denis, A. Vigan, G. Chauvin +35

Discovered almost 10 years ago, the giant planet 51 Eridani b is one of the least separated (0.2 arcsec) and faintest (J = 19.74 mag) directly imaged exoplanets known to date. Its…

The ExoGRAVITY survey: A K-band spectral library of giant exoplanet and brown dwarf companions

J. Kammerer, T. O. Winterhalder, S. Lacour +106

Direct observations of exoplanet and brown dwarf companions with near-infrared interferometry, first enabled by the dual-field mode of VLTI/GRAVITY, provide unique measurements of…
