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…
SCExAO/CHARIS and Gaia Direct Imaging and Astrometric Discovery of a Superjovian Planet 3--4 lambda/D from the Accelerating Star HIP 54515
Thayne Currie, Yiting Li, Mona El Morsy +28
We present the discovery of a superjovian planet around the young A5 star HIP 54515, detected using precision astrometry from the Hipparcos Gaia Catalogue of Accelerations and high…
Multi-band Spectral and Astrometric Characterization of the HIP 99770 b Planet with SCExAO/CHARIS and Gaia
Danielle Bovie, Thayne Currie, Mona El Morsy +12
We present and analyze follow-up, higher resolution ( 70) and band integral field spectroscopy of the superjovian exoplanet HIP 99770 b with SCExAO/CHARIS. Our ne…
Dynamical Analysis of the HD 169142 Planet-Forming Disk: Twelve Years of High-Contrast Polarimetry
Miles Lucas, Michael Bottom, Ruobing Dong +19
We present a dynamical analysis of the HD 169142 planet-forming disk based on high-contrast polarimetric imaging over a twelve-year observational period, offering insights into its…
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…
Dynamical and Atmospheric Characterization of the Substellar Companion HD 33632 Ab from Direct Imaging, Astrometry, and Radial-Velocity Data
Mona El Morsy, Thayne Currie, Danielle Bovie +17
We present follow-up SCExAO/CHARIS and -band (R 70) high-contrast integral field spectroscopy and Keck/NIRC2 photometry of directly-imaged brown dwarf companion HD 33…
SCExAO/CHARIS Multi-Wavelength, High-Contrast Imaging of the BD+45598 Debris Disk
Maria Vincent, Kellen Lawson, Thayne Currie +5
We present a multi-wavelength (1.16m-2.37m) view of the debris disk around BD+45598, using the Subaru Coronagraphic Extreme Adaptive Optics system paired with the Cor…
Testing magnetospheric accretion as an H emission mechanism of embedded giant planets: The case study for the disk exhibiting meridional flow around HD 163296
Yasuhiro Hasegawa, Taichi Uyama, Jun Hashimoto +7
Recent high-sensitivity observations reveal that accreting giant planets embedded in their parental circumstellar disks can emit H at their final formation stages. While the ori…
Direct Imaging and Astrometric Detection of a Gas Giant Planet Orbiting an Accelerating Star
Thayne Currie, G. Mirek Brandt, Timothy D. Brandt +31
Direct imaging of gas giant exoplanets provides key information on planetary atmospheres and the architectures of planetary systems. However, few planets have been detected in blin…
