The spiral arms in the young star IM Lupi’s planet-forming disk appear to stand still, not orbit as earlier reports suggested, and a faint, larger spiral may reach farther out. New findings also link red dwarf chemistry to the makeup of rocky planets, test a faster way to read WASP-77 b’s atmosphere, forecast sharper searches for shrinking hot-Jupiter orbits, and track changing gas around the young binary DQ Tau.

More about Star position in StellarGuide
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.
