Evidence for Color Dichotomy in the Primordial Neptunian Trojan Population

Hsing Wen Lin, David W. Gerdes, Stephanie J. Hamilton +45

In the current model of early Solar System evolution, the stable members of the Jovian and Neptunian Trojan populations were captured into resonance from the leftover reservoir of…

Rotation Periods, Inclinations, and Obliquities of Cool Stars Hosting Directly Imaged Substellar Companions: Spin-Orbit Misalignments are Common

Brendan P. Bowler, Quang H. Tran, Zhoujian Zhang +10

The orientation between a star's spin axis and a planet's orbital plane provides valuable information about the system's formation and dynamical history. For non-transiting planets…

An Outer Giant Planet or Brown Dwarf in the 51 Pegasi System?

Marvin Morgan, Brendan P. Bowler, Kyle Franson +15

51 Pegasi harbors the first confirmed extrasolar planet orbiting a Sun-like star. Decades of continued radial velocity (RV) observations have since uncovered signatures of an addit…

ELemental abundances of Planets and brown dwarfs Imaged around Stars (ELPIS): I. Potential Metal Enrichment of the Exoplanet AF Lep b and a Novel Retrieval Approach for Cloudy Self-luminous Atmospheres

Zhoujian Zhang, Paul Mollière, Keith Hawkins +10

AF Lep A+b is a remarkable planetary system hosting a gas-giant planet that has the lowest dynamical mass among directly imaged exoplanets. We present an in-depth analysis of the a…

Trans-Neptunian objects found in the first four years of the Dark Energy Survey

Pedro H. Bernardinelli, Gary M. Bernstein, Masao Sako +61

We present a catalog of 316 trans-Neptunian bodies detected by the Dark Energy Survey (DES). These objects include 245 discoveries by DES (139 not previously published) detected in…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems I: High Contrast Imaging of the Exoplanet HIP 65426 b from 2-16 m

Aarynn L. Carter, Sasha Hinkley, Jens Kammerer +108

We present JWST Early Release Science (ERS) coronagraphic observations of the super-Jupiter exoplanet, HIP 65426 b, with the Near-Infrared Camera (NIRCam) from 2-5 m, and with…
