Abstract

The Herschel Space Observatory was used to observe similar to 120 pre-main-sequence stars in Taurus as part of the GASPS Open Time Key project. Photodetector Array Camera and Spectrometer was used to measure the continuum as well as several gas tracers such as [O I] 63 mu m, [O I] 145 mu m, [C II] 158 mu m, OH, H2O, and CO. The strongest line seen is [O I] at 63 mu m. We find a clear correlation between the strength of the [O I] 63 mu m line and the 63 mu m continuum for disk sources. In outflow sources, the line emission can be up to 20 times stronger than in disk sources, suggesting that the line emission is dominated by the outflow. The tight correlation seen for disk sources suggests that the emission arises from the inner disk (
