RefPlanets: Search for reflected light from extra-solar planets with SPHERE/ZIMPOL
S. Hunziker, H. M. Schmid, D. Mouillet +55
RefPlanets is a guaranteed time observation (GTO) programme that uses the Zurich IMaging POLarimeter (ZIMPOL) of SPHERE/VLT for a blind search for exoplanets in wavelengths from 60…
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…
The detection and characterisation of 54 massive companions with the SOPHIE spectrograph -- 7 new brown dwarfs and constraints on the BD desert
F. Kiefer, G. Hébrard, J. Sahlmann +35
Brown-dwarfs are substellar objects with masses intermediate between planets and stars within about 13-80Mjup. While isolated BDs are most likely produced by gravitational collapse…
NAOMI: the adaptive optics system of the Auxiliary Telescopes of the VLTI
Woillez J., Abad J. A., Abuter R. +80
The tip-tilt stabilisation system of the 1.8 m Auxiliary Telescopes of the Very Large Telescope Interferometer was never dimensioned for robust fringe tracking, except when atmosph…
Calibration of quasi-static aberrations in exoplanet direct-imaging instruments with a Zernike phase-mask sensor. III. On-sky validation in VLT/SPHERE
A. Vigan, M. N'Diaye, K. Dohlen +12
Second-generation exoplanet imagers using extreme adaptive optics and coronagraphy have demonstrated their great potential for studying close circumstellar environments and for det…
Optical polarized phase function of the HR\,4796A dust ring
J. Milli, N. Engler, H. M. Schmid +24
The scattering properties of the dust originating from debris discs are still poorly known. The analysis of scattered light is however a powerful remote-sensing tool to understand…
