The helium triplet-to-singlet ratio in T Tauri stars.
Abstract
Summary. The He ilines at 5876 and 6678 are used to determine the triplet-to-singlet ratio for T Tauri stars DF Tau and BP Tau. The ratio is approximately 3. Line profiles and absolute intensities are presented. Key words: T Tauri stars helium lines
