Thermal evolution models for TOI-431 b and other ultra-short-period lava planets
Published: today
Researchers have modeled the atmospheric and surface conditions of five rocky exoplanets that orbit their stars very closely. These ultra-short-period planets, including TOI-431 b, likely host permanent magma oceans due to extreme temperatures. By si...
Sub-Earth-sized planet candidate observed around the red dwarf Gliese 774 A
Published: today
Data from the TESS space telescope reveals a sub-Earth-sized planet candidate orbiting within the Gliese 774 binary star system. Located 12.86 parsecs away, the signal likely originates from the primary star, Gliese 774 A. If confirmed, this world wo...

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