Addressing the low-wind effect with the Lyot-based low-order wavefront sensor on SCExAO
Garima Singh, Sebastien Vievard, Julien Lozi +5
The Low-Wind Effect (LWE) is a well-known issue that affects the coronagraphic capabilities of instruments optimized to take direct images of exoplanets. This effect is prominent i…
AO3k + SCExAO: on-sky wavefront quality and demonstration of novel WFS techniques with the double XAO system
Julien Lozi, Kyohoon Ahn, Vincent Deo +5
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system, fed by its upstream 3000-actuator "woofer" (AO3k), serves both as a platform for high contrast imaging (HCI) techn…
SCExAO/CHARIS High-Contrast Pre-Launch Vetting of Roman Coronagraph Technology Demonstration PSF Reference Stars
Thayne Currie, Jie Li, Mona El Morsy +9
We present deep, SCExAO/CHARIS high-contrast integral field spectroscopy and archival imaging of four candidate Roman Coronagraph PSF reference stars within/near the Roman Continuo…
Technology and Science Advancing Observations with Roman Coronagraph Informed by Ground-Based High-Contrast Imaging
Mona El Morsy, Thayne Currie, Brianna Lacy +10
The Roman Coronagraph technology demonstration focuses on achieving 10 contrasts within the instrument's dark hole and our ability to detect and characterize properties…
FIRST-PL: Commissioning the first visible photonic lantern spectrograph for sub-diffraction-limit astronomy on Subaru/SCExAO
Sebastien Vievard, Elsa Huby, Sylvestre Lacour +18
FIRST-PL (Fibered Imager foR a Single Telescope - Photonic Lantern) is a newly commissioned visible-light instrument on Subaru/SCExAO achieving spectroscopy below the diffraction l…
