Spectropolarimetry of the Classical T Tauri Star T Tauri

Spectropolarimetry of the Classical T Tauri Star T Tauri

High-resolution (R 60,000) circular spectropolarimetry of the classical T Tauri star T Tau is presented. The star was observed on 1997 November 21 and 22. Analyzing 12 photospheric absorption lines, the mean longitudinal magnetic field is found to be Bz = 12 ± 35 G. The 3 s upper limit of |Bz|
