Description

They both present a central absorption, very strong in DL Tau, in good agreement with the chromospheric assumption. The technique used allows short time variations of the profile to be detected

Abstract (French)

On publie les profils Hsub(α) non encore observes a moyenne resolution de deux etoiles T Tauri faibles de type spectral peu different K 5 et K 7. Tous deux presentent une absorption centrale qui est tres nette et intense dans le cas de l'etoile DL Tau, et en bon accord avec l'hypothese chromospherique. La technique utilisee permet la detection de variations rapides du profil au cours du tem
