Stellar companions sculpt hot Jupiter formation and spin-orbit evolution
Cheyanne Shariat, Kareem El-Badry, Songhu Wang +4
Stellar companions can drive hot-Jupiter (HJ) migration and spin-orbit misalignment, but their role in HJ formation remains uncertain. We construct a homogeneous census of resolved…
The Cephei System: Updated Orbits, Dynamical Architecture, and Limits on Additional Companions
Judah Van Zandt, Brendan P. Bowler, Michael Endl +18
The Cephei system hosts one of the first exoplanets discovered and is orbited by one of the closest known stellar companions to a planet-hosting star. Here, we derive updated o…
A High-Resolution Spectroscopic Survey of Directly Imaged Companion Hosts: III. Characterization of the Cold Imaged Planet Hosts AF Lep A and Indi A
Aneesh Baburaj, Quinn M. Konopacky, Christopher A. Theissen +3
JWST has enabled the measurement of carbon, oxygen, and sulfur abundances in the atmospheres of directly imaged planets. Interpretation of these abundances from a planet formation…
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…
Atmospheric Diversity of Giant Planet Analogs from 3-5um with SPHEREx
Rocio Kiman, Brendan P. Bowler, Jerry W. Xuan +2
The emergent spectra of giant planets peak at thermal infrared wavelengths (3-5um) and possess atmospheric features in this regime that trace carbon chemistry, vertical mixing, clo…
Discovery of an Exterior Third Planet Orbiting Pictoris
Aidan Gibbs, Jean-Baptiste Ruffio, Alexis Bidot +9
We report the discovery of Pictoris d ( Pic d), a third giant planet in the Pictoris system, which now becomes only the second directly imaged system with more than two…
