Abstract
We have detected the high-density, high-temperature, neutral material within 10-200 R ○. of five young stars through high-resolution (20-40 km s −1 ) spectroscopy of the first overtone bands of CO at 2.3 μm. We find a remarkable diversity in the band head profiles toward these sources, ranging from distinctly double-peaked (DG Tau), through broad bumps with emission extending up to 200 km s −1 from the stellar velocity (WL 16, NGC 2024 IRS 2, and S106 IRS 4), to narrow lines having a FWHM velocity of ∼50 km s −1 (SVS 13)
