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…
The KPF SURFS-UP Survey I: Transmission Spectroscopy of WASP-76 b
Aaron Householder, Fei Dai, Aurora Kesseli +25
We introduce the KPF SURFS-UP (Spectroscopy of the Upper-atmospheres and ReFractory Species in Ultra-hot Planets) Survey, a high-resolution survey to investigate the atmospheric co…
Hydrogen airglow from an escaping ultrahot Jupiter atmosphere
Yapeng Zhang, Chenliang Huang, Aaron Householder +17
Intense high-energy irradiation of close-in gaseous exoplanets drives the rapid escape of their atmospheres, fundamentally shaping planetary demographics. While atmospheric loss is…
CO and potential variability in Pictoris b with GRAVITY+
Antonia von Stauffenberg, Jonas Sauter, Paul Mollière +18
The CO/CO ratio was introduced as an indicator for where in the disk a planet has formed. Previously a lower value compared to the host star's was suggested to show t…
Hyperon-Nucleon Spectrometer
Xiaozhi Bai, Xu Cao, Zhe Cao +237
Chirality lies at the heart of low-energy QCD, governing the symmetry structure that shapes hadron masses and strong interaction dynamics. Among the most compelling open questions…
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…
