Updating the SCExAO/CHARIS polarimetric calibration following the Nasmyth beam-switcher upgrade

Thomas McIntosh, Manxuan Zhang, Briley L. Lewis +18

Subaru/SCExAO/CHARIS enables near-infrared integral field spectropolarimetry. Quantitative polarimetry is useful for a variety of science cases, particularly measurements related t…

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…

Combining spectroscopy and wavefront control at deep contrast with photonic lanterns

Mona El Morsy, Olivier Guyon, Barnaby Norris +7

HWO aims to directly image objects orbiting Sun-like stars, using a 6-m telescope capable of high-contrast imaging () and spectroscopy to search for biosignatures in plan…

A Roman Coronagraph Spectroscopic Mode Demonstration

Thayne Currie, Brianna Lacy, Yiting Li +5

We propose 730 nm high-contrast spectroscopic observations of selected self-luminous directly-imaged planets as a key test of the Roman Coronagraph's planet characterization capabi…

Decisively Demonstrating Roman CGI's TTR5 Requirement by Reimaging a Newly-Discovered Brown Dwarf Orbiting a Bright Accelerating Star

Thayne Currie, Mona El Morsy, Brianna Lacy +3

We propose Roman Coronagraph project HLC/575 nm observations of a newly-discovered brown dwarf (HIP 71618 B) from the Subaru/OASIS survey of young accelerating stars, which is supp…

The HIP 54515 b Superjovian Planet as an Early, Critical Look at the Roman Coronagraph's Performance in the Faint Target Star, Small IWA Limit

Thayne Currie, Yiting Li, Brianna Lacy +4

The Roman Coronagraph's capabilities in the faint star, small IWA limit has enormous scientific (programmatic) impacts. Testing its performance in this limit provides a first look…

Demonstrating Improved Contrast on the Roman Coronagraph with Spatial Linear Dark Field Control

Thayne Currie, Olivier Guyon, Ruslan Belikov +2

The baseline contrast floor from the Roman Coronagraph's High-Order Wavefront Sensing and Control strategy likely degrades over the course of time, requiring periodic recalibration…

A Striking First Impression: CGI Commissioning Observations of the AB Aurigae Protoplanetary System

Thayne Currie, Kellen Lawson, Erica Dykes +1

For one of the first set of Roman Coronagraph project images, we propose to target AB Aurigae. AB Aurigae is a complex and visually stunning system, surrounded by a gas rich protop…
