What Does CTTS Stand For?
CTTS stands for Classical T Tauri Star
CTTS, or Classical T Tauri Star, refers to a specific type of young stellar object that is in the pre-main-sequence stage of stellar evolution. These stars are typically less than a few million years old and exhibit significant variability in brightness due to unstable accretion processes from a surrounding protoplanetary disk. CTTS are characterized by strong emission lines in their spectra, indicating active stellar winds and outflows, as well as the presence of dust and gas in their vicinity. They are essential for understanding the formation and early development of stars and planetary systems.
