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…
On-sky speckle nulling demonstration at small angular separation with SCExAO
Frantz Martinache, Olivier Guyon, Nemanja Jovanovic +7
This paper presents the first on-sky demonstration of speckle nulling, which was achieved at the Subaru Telescope in the context of the Subaru Coronagraphic Extreme Adaptive Optics…
The Subaru Coronagraphic Extreme Adaptive Optics Imager: First Results and On-Sky Performance
Thayne Currie, Olivier Guyon, Frantz Martinache +6
We present new on-sky results for the Subaru Coronagraphic Extreme Adaptive Optics imager (SCExAO) verifying and quantifying the contrast gain enabled by key components: the closed…
New Techniques for High-Contrast Imaging with ADI: the ACORNS-ADI SEEDS Data Reduction Pipeline
Timothy D. Brandt, Michael W. McElwain, Edwin L. Turner +44
We describe Algorithms for Calibration, Optimized Registration, and Nulling the Star in Angular Differential Imaging (ACORNS-ADI), a new, parallelized software package to reduce hi…
A dual-mask coronagraph for observing faint companions to binary stars
Eric Cady, Michael McElwain, N. Jeremy Kasdin +1
Observations of binary stars for faint companions with conventional coronagraphic methods are challenging, as both targets will be bright enough to obscure any nearby faint compani…
