Class of stars Sub-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. Brown dwarfs of spectral class Y are the coolest and only a few of them have been discovered so far.

Stellar Brief

27. 10. 2026

V1298 Tau b showed helium absorption during all four observed transits across four years, but its active host star may affect the signal. The latest findings also point to silicate clouds on TOI-561 b, a warped dust ring around CQ Tau, and a giant planet candidate near Boyajian's star that may be surrounded by vast rings. New atmospheric models reveal why gas compositions can vary across hot giant planets.

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.
