A class of young, pre-main sequence stars less than 10 million years old that are still contracting and haven't begun stable hydrogen fusion. They often show strong stellar winds, variability, and are associated with star-forming regions.
Named after T Tauri, the prototype star in the constellation Taurus, discovered by John Russell Hind in 1852. The 'T' designation follows variable star naming conventions, with T Tauri being the first variable found in Taurus.
T Tauri stars are cosmic teenagers - they're still growing up and haven't settled into the stable adult life of main sequence stars! These stellar youngsters are often surrounded by protoplanetary disks where planets are forming, making them natural laboratories for studying how solar systems are born.
