A star’s hidden vibrations, a planet’s escaping helium, and worlds wrapped in shifting clouds reveal how much can be learned from changing light. Recent observations trace WASP 121’s surface motions in infrared for the first time, map the uneven clouds of WASP-43 b, and catch helium streaming ahead of TOI-3884 b. Light patterns also place the massive star HD 74371 on a return journey toward bluer colors after its red supergiant phase, while search interest spans Proxima Centauri b, Alpha Centauri, and many other stellar neighbors.
Data in Stellar Catalog come from trusted scientific sources. Primary source is Gaia space telescope mapping the stars in Milky Way. Other sources include research papers, Simbad catalog and Exoplanet.eu database.
Objects listed in the Stellar Catalog often have values that are estimates. These estimates are determined using their known characteristics, such as spectral type, brightness across different wavelengths, distance from a star, and other factors.
Stellar Catalog is continuously updated with new information from research papers. Stellar and planetary data are validated by automatic processes as well as humans.
