A Sulfur-Rich Atmosphere for the Young Jupiter Analog AF Lep b Reveals Significant Solid Accretion
Jerry W. Xuan, William O. Balmer, Yayaati Chachan +25
AF Lep b is one of the closest analogs to Jupiter in terms of mass () and semi-major axis ( AU) amenable to spectroscopic characterization. We present JWST/NIR…
Searching for the Third Wheel: High-Contrast Imaging Constraints on Tertiaries to Black Hole and Neutron Star Binaries
Pranav Nagarajan, Kareem El-Badry, Aniket Sanghi
The authors performed deep adaptive‑optics near‑infrared imaging of several black‑hole and neutron‑star binaries to look for tertiary companions, finding no convincing detections a…
Worlds Next Door. IV. Mapping the Late Stages of Giant Planet Evolution with a Precise Dynamical Mass and Luminosity for Ind Ab
Aniket Sanghi, William Thompson, James Mang +21
We present new JWST/NIRCam 4-5 m (F410M, F430M) and JWST/MIRI 18-25 m (F1800W, F2100W, F2550W) imaging detections of the nearby (3.6 pc) cold (275 K) gas giant exoplanet $Î…
Worlds Next Door. III. Indirect Evidence for Enhanced Atmospheric Metallicity and/or the Presence of Water Clouds in the Nearest Jupiter-analog Eri b
Aniket Sanghi, James Mang, Jorge Llop-Sayson +12
We present the most sensitive direct imaging search for the nearest ( pc) Jupiter-analog exoplanet, Eri b, with JWST/NIRCam coronagraphy between 4-5 m (F444W). We…
Keck Observations in the INfrared of Taurus and Oph Exoplanets And Ultracool dwarfs (KOINTREAU) II: Two Young Bound Companions to Ophiuchus Stars
Samuel Walker, Michael C. Liu, Dimitri Mawet +4
We present the second set of discoveries from Keck Observations in the INfrared of Taurus and Oph Exoplanets And Ultracool dwarfs (KOINTREAU), an adaptive optics survey of you…
HD 143811 AB b: A Directly Imaged Planet Orbiting a Spectroscopic Binary in Sco-Cen
Nathalie K. Jones, Jason J. Wang, Eric L. Nielsen +51
We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD…
