Tracing the Influence of Distant companions on Exoplanetary Systems (TIDES) I. Highly Eccentric and Misaligned Binary Companions to Hot Jupiters
Marvin Morgan, Jerry W. Xuan, Brendan P. Bowler +9
The origin of hot Jupiters remains an open question. A significant fraction reside in binary or multiple star systems, suggesting that stellar companions may play an important role…
Astrometric Evidence for Outer Giant Planets in Known Exoplanet Systems
Clarissa R. Do Ó, William Thompson, Dori Blakely +19
Outer giant planets can influence the formation and dynamical evolution of their planetary systems. However, their long orbital periods make them difficult to detect using transit…
Worlds Next Door. V. A Candidate Solar System Scale Super-Jupiter in the 61 Cygni Binary System
Aniket Sanghi, Billy Quarles, Andrea S. J. Lin +16
We present new constraints on a candidate third companion in the 61 Cygni binary system-one of the closest neighbors to our solar system (3.5 pc), the first stars to have a measure…
The JWST Sub-Jupiters Survey: Direct Imaging Discovery of a Giant Planet and a Debris Disk Around the Young M-dwarf RX J0534.0-0221
Rodrigo Ferrer-Chavez, Jason J. Wang, Kevin Wagner +47
We present the discovery of RX J0534.0-0221 b, a giant planet orbiting an M-dwarf star in the Pictoris moving group. RX J0534 was originally observed with JWST/NIRCam in the F4…
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
Black holes (BHs) and neutron stars (NSs) with low-mass stellar companions challenge traditional isolated binary evolution models, motivating hierarchical triple evolution as a pro…
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 …
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 a…
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 youn…
