Polarization aberrations in next-generation giant segmented mirror telescopes (GSMTs) I. Effect on the coronagraphic performance
Ramya M. Anche, Jaren N. Ashcraft, Sebastiaan Y. Haffert +8
Next-generation large segmented mirror telescopes are expected to perform direct imaging and characterization of Earth-like rocky planets, which requires contrast limits of $10^{-7…
Original use of MUSE's laser tomography adaptive optics to directly image young accreting exoplanets
Julien H. Girard, Jozua de Boer, Sebastiaan Haffert +8
We present recent results obtained with the VLT/MUSE Integral Field Spectrograph fed by the 4LGSF and its laser tomography adaptive optics module GALACSI. While this so-called narr…
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 polarimetric imaging mode of VLT/SPHERE/IRDIS I: Description, data reduction and observing strategy
J. de Boer, M. Langlois, R. G. van Holstein +31
Context. Polarimetric imaging is one of the most effective techniques for high-contrast imaging and characterization of protoplanetary disks, and has the potential to be instrument…
SPHERE / ZIMPOL high resolution polarimetric imager. I. System overview, PSF parameters, coronagraphy, and polarimetry
H. M. Schmid, A. Bazzon, R. Roelfsema +59
We describe the Zurich Imaging Polarimeter (ZIMPOL), the visual focal plane subsystem of the SPHERE "VLT planet finder", which pushes the limits of current AO systems to shorter wa…
