Abstract

Two high-Galactic latitude molecular clouds (HLC) in the region of IC 2118, the Witch Head Nebula, appear to be forming stars (Kun et al. 2004). Star formation in HLCs, while rare, may be the origin of some of the apparently isolated T Tauri stars revealed by ROSAT. At only 210 pc away, the clouds in IC 2118 are thought to be excited by Rigel. Kun et al. (2004) reported the discovery of three T Tauri stars in this region. Our 2005 pilot project surveyed a 15x15 arc-minute region at the head of the cloud and approximately quadrupled the number of suspected young objects in this region (Spuck et al. 2005). With additional Spitzer Telescope time in 2006, we observed 2 square degrees further along the nebula. Using color-color plots, we have identified many candidate young objects throughout the nebula. In this poster, we will present color-color plots and SEDs of these stars, criteria for their selection, and discuss follow-up observations at other wavelengths to confirm the status of the suspected young objects. These observations are part of the Spitzer Space Telescope Research Program for Teachers and Students.
