1112.6181 (C. R. Cowley et al.)

The narrow, inner CO ring around the magnetic Herbig Ae star, HD 101412    [PDF]

C. R. Cowley, S. Hubrig, F. Castelli, B. Wolff
We describe and model emission lines in the first overtone band of CO in the magnetic Herbig Ae star HD 101412. High-resolution CRIRES spectra reveal unusually sharp features which suggest the emission is formed in a thin disk centered at 1 AU with a width 0.32 AU or less. A wider disk will not fit the observations. Previous observations have reached similar conclusions, but the crispness of the new material brings the emitting region into sharp focus.
