We present Submillimeter Array observations of H2CO and N2H + emission in the disks around the T Tauri star TW Hya and the Herbig Ae star HD 163296 at 2–6 resolution and discuss the distribution of these species with respect to CO freeze-out. The H2CO and N2H + emission toward HD 163296 does not peak at the continuum emission center that marks the stellar… CONTINUE READING
