| dc.description | We present high spectral-resolution optical spectra of 49 Herbig Ae/Be stars in a search for the [O I] 6300.2 A line. The vast majority of the stars in our sample show narrow (FWHM < 100 km/s) emission lines, centered on the stellar radial velocity. Some stars in our sample show double-peaked lines profiles, with peak-to-peak separations of about 10 km/s. The presence and strength of the [O I] line emission appears to be well correlated with the far-infrared energy distribution of each source: stars with a strong excess at 60 micron have in general stronger [O I] emission than stars with weaker 60 micron excesses. We interpret the observed [O I] 6300.2 A line profiles as arising in the surface layers of the protoplanetary disks surrounding Herbig Ae/Be stars. | |
