Worlds Next Door. V. A Candidate Solar System Scale Super-Jupiter in the 61 Cygni Binary System

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 measured parallax, and two of the most favorable targets for habitable zone exo-Earth searches with future direct imaging missions.

Confirmation of the Low-eccentricity Warm Jupiter HD 278555 b with NEID

The study of warm Jupiters is crucial to understanding the processes that govern giant-planet formation and migration. These planets sit at the boundary between cold giant planets and hot Jupiters, and studying their orbital properties, including period, eccentricity, and spin–orbit alignment, can offer insights into t...
