Planet(esimal)s Around Stars with TESS (PAST) III: A Search for Triplet He I in the Atmospheres of Two 200 Myr-old Planets
Eric Gaidos, Teruyuki Hirano, Rena A. Lee +13
We report a search for excess absorption in the 1083.2 nm line of ortho (triplet) helium during transits of TOI-1807b and TOI-2076b, 1.25 and 2.5R planets on 0.55- an…
Spatially resolved observations of Europa's surface with Subaru/IRCS at 1.0-1.8 : Upper limits to the abundances of hydrated Cl-bearing salts
Shuya Tan, Yasuhito Sekine, Masayuki Kuzuhara
Recent infrared observations at 1.5-4.0 using large ground-based telescopes have suggested that Cl-bearing salts are likely present on Europa's surface as non-ice materials. T…
Zodiacal Exoplanets in Time (ZEIT) XII: A Directly-Imaged Planetary-Mass Companion to a Young Taurus M Dwarf Star
E. Gaidos, T. Hirano, A. L. Kraus +21
We report the discovery of a resolved (0".9) substellar companion to a member of the 1-5 Myr Taurus star-forming region. The host star (2M0437) is a single mid-M type ($T_{eff}\app…
A New Type of Exoplanet Direct Imaging Search: The SCExAO/CHARIS Survey of Accelerating Stars
Thayne Currie, Timothy Brandt, Masayuki Kuzuhara +12
We present first results from a new exoplanet direct imaging survey being carried out with the Subaru Coronagraphic Extreme Adaptive Optics project (SCExAO) coupled to the CHARIS i…
37 New Validated Planets in Overlapping K2 Campaigns
J. P. de Leon, J. Livingston, M. Endl +24
We analysed 68 candidate planetary systems first identified during Campaigns 5 and 6 (C5 and C6) of the NASA \textit{K2} mission. We set out to validate these systems by using a su…
First Detection of Hydroxyl Radical Emission from an Exoplanet Atmosphere: High-dispersion Characterization of WASP-33b using Subaru/IRD
Stevanus K. Nugroho, Hajime Kawahara, Neale P. Gibson +23
We report the first detection of a hydroxyl radical (OH) emission signature in the planetary atmosphere outside the solar system, in this case, in the day-side of WASP-33b. We anal…
