IR calcium triplet lines in some stars of the T Tauri type and related objects
Abstract
Photoelectric spectrum scanner observations of 10 T Tauri type stars are discussed. The IR calcium triple line profiles are determined for six of the stars from the spectrograms obtained. A pronounced seasonal and nighttime variability of the line profiles is noted and is attributed to the complex dynamics of the radiant gas.
