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…
Multiband polarimetric imaging of HD 34700 with SCExAO/CHARIS
Minghan Chen, Kellon Lawson, Timothy D. Brandt +5
We present Subaru/SCExAO + CHARIS broadband (JHK) integral field spectroscopy of HD 34700 A in polarized light. CHARIS has the unique ability to obtain polarized integral field ima…
A Survey of Protoplanetary Disks Using the Keck/NIRC2 Vortex Coronagraph
Nicole L. Wallack, Jean-Baptiste Ruffio, Garreth Ruane +34
Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations of protoplanetary disks in the millimeter continuum have shown a variety of radial gaps, cavities, and spira…
Gliese 12 b: A temperate Earth-sized planet at 12 pc ideal for atmospheric transmission spectroscopy
M. Kuzuhara, A. Fukui, J. H. Livingston +103
Recent discoveries of Earth-sized planets transiting nearby M dwarfs have made it possible to characterize the atmospheres of terrestrial planets via follow-up spectroscopic observ…
Direct-imaging Discovery of a Substellar Companion Orbiting the Accelerating Variable Star, HIP 39017
Taylor L. Tobin, Thayne Currie, Yiting Li +23
We present the direct-imaging discovery of a substellar companion (a massive planet or low-mass brown dwarf) to the young, Doradus-type variable star, HIP 39017 (HD 65526). The…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems V: Do Self-Consistent Atmospheric Models Represent JWST Spectra? A Showcase With VHS 1256 b
Simon Petrus, Niall Whiteford, Polychronis Patapis +119
The unprecedented medium-resolution (R~1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (140+/-20Myr) low-mass (12-20MJup) L-T transition (L7) com…
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…
