The vector-apodizing phase plate coronagraph: design, current performance, and future development
D. S. Doelman, F. Snik, E. H. Por +50
Over the last decade, the vector-apodizing phase plate (vAPP) coronagraph has been developed from concept to on-sky application in many high-contrast imaging systems on 8-m class t…
Focal Plane Wavefront Sensing on SUBARU/SCExAO
Sebastien Vievard, Steven P. Bos, Frederic Cassaing +20
Focal plane wavefront sensing is an elegant solution for wavefront sensing since near-focal images of any source taken by a detector show distortions in the presence of aberrations…
On-sky verification of Fast and Furious focal-plane wavefront sensing: Moving forward toward controlling the island effect at Subaru/SCExAO
Steven P. Bos, Sébastien Vievard, Michael J. Wilby +8
High-contrast imaging (HCI) observations of exoplanets can be limited by the island effect (IE). On the current generation of telescopes, the IE becomes a severe problem when the g…
Overview of focal plane wavefront sensors to correct for the Low Wind Effect on SUBARU/SCExAO
Sebastien Vievard, Steven Bos, Frederic Cassaing +15
The Low Wind Effect (LWE) refers to a phenomenon that occurs when the wind speed inside a telescope dome drops below m/s creating a temperature gradient near the telescope spide…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes III. Technology opportunities and pathways
Frans Snik, Olivier Absil, Pierre Baudoz +30
The Optimal Optical CoronagraphWorkshop at the Lorentz Center in September 2017 in Leiden, the Netherlands gathered a diverse group of 25 researchers working on exoplanet instrumen…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes II. Common path wavefront sensing/control and Coherent Differential Imaging
Nemanja Jovanovic, Olivier Absil, Pierre Baudoz +28
The Optimal Optical Coronagraph (OOC) Workshop held at the Lorentz Center in September 2017 in Leiden, the Netherlands, gathered a diverse group of 25 researchers working on exopla…
Review of high-contrast imaging systems for current and future ground- and space-based telescopes I. Coronagraph design methods and optical performance metrics
G. Ruane, A. Riggs, J. Mazoyer +29
The Optimal Optical Coronagraph (OOC) Workshop at the Lorentz Center in September 2017 in Leiden, the Netherlands gathered a diverse group of 25 researchers working on exoplanet in…
Modeling coronagraphic extreme wavefront control systems for high contrast imaging in ground and space telescope missions
Jennifer Lumbres, Jared Males, Ewan Douglas +17
The challenges of high contrast imaging (HCI) for detecting exoplanets for both ground and space applications can be met with extreme adaptive optics (ExAO), a high-order adaptive…
Focal plane wavefront sensing and control strategies for high-contrast imaging on the MagAO-X instrument
Kelsey Miller, Jared R. Males, Olivier Guyon +14
The Magellan extreme adaptive optics (MagAO-X) instrument is a new extreme adaptive optics (ExAO) system designed for operation in the visible to near-IR which will deliver high co…
First direct detection of a polarized companion outside of a resolved circumbinary disk around CS Cha
C. Ginski, M. Benisty, R. G. van Holstein +18
In the present study we aim to investigate the circumstellar environment of the spectroscopic binary T Tauri star CS Cha. From unresolved mid- to far-infrared photometry it is pred…
Laboratory verification of 'Fast & Furious' phase diversity: Towards controlling the low wind effect in the SPHERE instrument
Michael J. Wilby, Christoph U. Keller, Jean-Francois Sauvage +4
The low wind effect (LWE) refers to a characteristic set of quasi-static wavefront aberrations seen consistently by the SPHERE instrument when dome-level wind speeds drop below 3 m…
The coronagraphic Modal Wavefront Sensor: a hybrid focal-plane sensor for the high-contrast imaging of circumstellar environments
Michael J. Wilby, Christoph U. Keller, Frans Snik +2
The raw coronagraphic performance of current high-contrast imaging instruments is limited by the presence of a quasi-static speckle (QSS) background, resulting from instrumental no…
