SCExAO/CHARIS Spectroscopic Characterization of Cloudy L/T Transition Companion Brown Dwarf HIP 93398 B
Briley Lewis, Yiting Li, Aidan Gibbs +10
Brown dwarfs with measured dynamical masses and spectra from direct imaging are benchmarks that anchor substellar atmosphere cooling and evolution models. We present Subaru SCExAO/…
Spectral characterization of a 3-port photonic lantern for application to spectroastrometry
Yoo Jung Kim, Michael P. Fitzgerald, Jonathan Lin +10
Spectroastrometry, which measures wavelength-dependent shifts in the center of light, is well-suited for studying objects whose morphology changes with wavelength at very high angu…
Visible-Light High-Contrast Imaging and Polarimetry with SCExAO/VAMPIRES
Miles Lucas, Barnaby Norris, Olivier Guyon +17
We present significant upgrades to the VAMPIRES instrument, a visible-light (600 nm to 800 nm) high-contrast imaging polarimeter integrated within SCExAO on the Subaru telescope. K…
SCExAO/CHARIS Near-Infrared Scattered-Light Imaging and Integral Field Spectropolarimetry of the AB Aurigae Protoplanetary System
Erica Dykes, Thayne Currie, Kellen Lawson +21
We analyze near-infrared integral field spectropolarimetry of the AB Aurigae protoplanetary disk and protoplanet (AB Aur b), obtained with SCExAO/CHARIS in 22 wavelength channels c…
Design, scientific goals, and performance of the SCExAO survey for planets around accelerating stars
Mona El Morsy, Thayne Currie, Masayuki Kuzuhara +25
We describe the motivation, design, and early results for our 42-night, 125 star Subaru/SCExAO direct imaging survey for planets around accelerating stars. Unlike prior large surve…
Spectral interferometric wavefront sensing: a solution for petalometry at Subaru/SCExAO
Vincent Deo, Sebastien Vievard, Manon Lallement +12
The petaling effect, induced by pupil fragmentation from the telescope spider, drastically affects the performance of high contrast instruments by inducing core splitting on the PS…
