Description

A high dispersion AAT spectrogram sets an upper limit on the [Fe x] emission line lambda 6374.5 A in the T Tauri star RU Lupi. The intensity of any 106 K corona in this star is less than 600 times that of the Sun compared to a chromosphere and transition region of 3 x 103 to 2 x 105 K gas 106 times stronger than the Sun's. The important theoretical implications are noted. (author)
