Class of stars Red giant

White dwarfs are the hot, extremely dense stellar remnants left behind by stars that originally had masses between about 0.5 and 8 times the mass of the Sun during their main sequence lifetimes. After exhausting their nuclear fuel, these stars shed their outer layers and leave behind a compact core. Although white dwarfs contain between roughly 0.2 and 1.44 solar masses, this mass is packed into a volume comparable to that of an Earth-sized planet, making them some of the densest objects in the Universe.

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.
