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

28. 10. 2026

WISE J1517+05 flashes powerful radio bursts every 1.149 hours, making it one of the fastest-spinning ultracool dwarfs detected in radio waves. The latest reports also explore how transit changes can reveal a hidden planet in Kepler-88 and map a possible hotspot on WD 1202-024 B. Other findings track helium in V1298 Tau b’s atmosphere and a warped dust ring around CQ Tau.

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.
