A subgiant is a term used to describe a luminous star that is typically running out of hydrogen for nuclear fusion and is thus departing from the main sequence. These stars are classified as Yerkes luminosity class IV.

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.
