Line Structure in the Spectrum of FU Orionis
P. P. Petrov, G. H. Herbig
New high-resolution spectra of FU Ori, obtained with the HIRES spectrograph at the Keck I telescope in 2003-2006, make it possible to compare the optical line profiles with those p…
Unveiling extremely veiled T Tauri stars
G. F. Gahm, F. M. Walter, H. C. Stempels +2
Photospheric absorption lines in classical T Tauri stars (CTTS) are weak compared to normal stars. This so-called veiling is normally identified with an excess continuous emission…
High-Resolution Spectroscopy of FUors
G. H. Herbig, P. P. Petrov, R. Duemmler
High-resolution spectroscopy was obtained of the FUors FU Ori and V1057 Cyg between 1995 and 2002 with SOFIN at NOT and with HIRES at Keck I. During those years FU Ori remained abo…
Eclipses by circumstellar material in the T Tauri star AA Tau. II. Evidence for non-stationary magnetospheric accretion
J. Bouvier, K. N. Grankin, S. H. P. Alencar +12
We report the results of a synoptic study of the photometric and spectroscopic variability of the classical T Tauri star AA Tau on timescales ranging from a few hours to several we…
