Active focal-plane coronagraphy with liquid-crystal spatial-light modulators: Broadband contrast performance in the visible
J. G. Kuhn, P. Patapis
The technological progress in spatial-light modulators (SLM) technology has made it possible to use those devices as programmable active focal-plane phase coronagraphic masks, open…
Molecular mapping of the PDS70 system: No molecular absorption signatures from the forming planet PDS70 b
G. Cugno, P. Patapis, T. Stolker +7
Aims. We aim to detect molecules in the atmosphere of the young forming companion PDS70 b by searching for atmospheric absorption features typical of substellar objects. Methods. W…
SLM-based Active Focal-Plane Coronagraphy: Status and future on-sky prospects
Jonas G. Kühn, Laurent Jolissaint, Audrey Bouxin +1
We recently started to investigate how liquid-crystal on silicon (LCOS) spatial light modulator (SLM) would perform as programmable focal-plane phase mask (FPM) coronagraphs. Such…
The Fast Atmospheric Self-Coherent Camera Technique: Laboratory Results and Future Directions
Benjamin L. Gerard, Christian Marois, Raphaël Galicher +3
Direct detection and detailed characterization of exoplanets using extreme adaptive optics (ExAO) is a key science goal of future extremely large telescopes (ELTs). However, wavefr…
A simple optimized amplitude pupil mask for attempting to direct imaging of Proxima b with SPHERE/ZIMPOL at VLT
Polychronis Patapis, Jonas Kühn, Hans Martin Schmid
Proxima b is a terrestrial exoplanet orbiting in the habitable zone of our closest star Proxima Centauri. The separation between the planet and the star is about 40 mas and this is…
SLM-based Digital Adaptive Coronagraphy: Current Status and Capabilities
Jonas Kuhn, Polychronis Patapis, Xin Lu +1
Active coronagraphy is deemed to play a key role for the next generation of high-contrast instruments, notably in order to deal with large segmented mirrors that might exhibit time…
