Abstract:
We explore the high-resolution
(Λ/ΔΛ=25000;Δv=12km/s) M-band
(4.7-5.1µm) spectra of several disk-dominated Herbig Ae (HAe)
systems: AB Aur, MWC 758, MWC 480, HD 163296, and VV Ser.
Description:
The Herbig Ae stars AB Aur (spectral type A0), MWC 480 (A5),
MWC 758 (A8), HD 163296 (A1), and VV Ser (A0) were observed with
NIRSPEC at the Keck II telescope on several observing runs between
2001 January and 2003 July.
