Class of stars Brown dwarf

Brown dwarfs are not really stars, because there is no thermonuclear fusion in their core. These objects are smaller and cooler than stars, but too massive to be considered planets

Stellar Brief

24. 10. 2026

The changing light of blue supergiant HD 74371 points to a dramatic turn in its life: the star appears to be moving blueward after a red-supergiant phase. Other fresh findings reveal helium escaping from an exoplanet, infrared rhythms on WASP 121, shifting radio and X-ray emissions from young V1298 Tauri, and clouds across WASP-43 b.

About Stellar Catalog

Working with real data

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.

Estimated values

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.

Fresh and validated

Stellar Catalog is continuously updated with new information from research papers. Stellar and planetary data are validated by automatic processes as well as humans.
