wide binary Archives

Our target wide binaries are marked with colored circles (primaries) and triangles (secondaries) in the 2MASS (K, J − K) and Gaia (G, BP − RP) CMDs. Blue, orange, green, and red denote HD 20782/HD 20781, WASP-160 A/WASP-160 B, K2-54/K2-54 B, and WASP-127/TYC 4916-897-1 pairs, respectively, with the same color scheme adopted in subsequent figures. Grey circles and triangles indicate our initial candidate systems of planet-hosting wide binaries, while the smaller background symbols represent all reported planet-hosting stars to date. The two components of each binary are connected with solid and dotted lines. -- astro-ph.SR

Chemical Signatures Of Planetary Systems In Their Host Stars. Near-infrared Spectroscopy Of Four Planet-hosting Wide Binaries

by Keith CowingMay 14, 2026May 14, 2026

An important open question in exoplanet studies is whether planets leave detectable chemical fingerprints on their host stars. While several studies have suggested possible planetary chemical signatures in planet-hosting stars, […]
