Socio-demographic study of the exoplanet direct imaging community
Lucie Leboulleux, Élodie Choquet, Elsa Huby +2
Astronomy and science are fields in which specific groups remain under-represented despite multiple studies that investigate this issue and propose solutions. In this article, we a…
An H-band Vector Vortex Coronagraph for the Subaru Coronagraphic Extreme-Adaptive Optics System
Jonas Kühn, Eugene Serabyn, Julien Lozi +11
The vector vortex is a coronagraphic imaging mode of the recently commissioned Subaru Coronagraphic Extreme-Adaptive Optics (SCExAO) platform on the 8-m Subaru Telescope. This mult…
The Subaru Coronagraphic Extreme Adaptive Optics system: enabling high-contrast imaging on solar-system scales
N. Jovanovic, F. Martinache, O. Guyon +35
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is a multipurpose high-contrast imaging platform designed for the discovery and detailed characterization of ex…
On-sky demonstration of low-order wavefront sensing and control with focal plane phase mask coronagraphs
Garima Singh, Julien Lozi, Olivier Guyon +6
The ability to characterize exoplanets by spectroscopy of their atmospheres requires direct imaging techniques to isolate planet signal from the bright stellar glare. One of the li…
Lyot-based Low Order Wavefront Sensor: Implementation on the Subaru Coronagraphic Extreme Adaptive Optics System and its Laboratory Performance
Garima Singh, Olivier Guyon, Pierre Baudoz +5
High throughput, low inner working angle (IWA) phase masks coronagraphs are essential to directly image and characterize (via spectroscopy) earth-like planets. However, the perform…
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…
Lyot-based Low Order Wavefront Sensor for Phase-mask Coronagraphs: Principle, Simulations and Laboratory Experiments
Garima Singh, Frantz Martinache, Pierre Baudoz +4
High performance coronagraphic imaging of faint structures around bright stars at small angular separations requires fine control of tip, tilt and other low order aberrations. When…
Lyot-based Ultra-Fine Pointing Control System for Phase Mask Coronagraphs
Garima Singh, Frantz Martinache, Pierre Baudoz +3
High performance coronagraphic imaging at small inner working angle requires efficient control of low order aberrations. The absence of accurate pointing control at small separatio…
SCExAO as a precursor to an ELT exoplanet direct imaging instrument
Nemanja Jovanovic, Olivier Guyon, Frantz martinache +11
The Subaru Coronagraphic Extreme AO (SCExAO) instrument consists of a high performance Phase Induced Amplitude Apodisation (PIAA) coronagraph combined with an extreme Adaptive Opti…
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…
