Surprising DR Tau .
Abstract
New spectroscopic observations of the peculiar T Tauri star DR Tauri show that strong qualitative changes in the Balmer line profiles can occur within 24 hours. Furthermore, on one plate ordinary P Cygni profiles (suggesting mass-outflow) and inverse P Cygni profiles (suggesting mass-infall) have been observed to occur in the same spectrogram at different Balmer lines.
