Scientific paper

As part of an on-going study of translucent interstellar clouds at high galactic latitude, we have completed the first stage of a search for new evidence of high-latitude star formation. We obtained near-infrared photometry of potential high-latitude young stellar objects that were selected on the basis of their IRAS colors. In addition to many objects whose youth was previously known, we identify eight new candidates with near-infrared excess and spectral energy distributions that are characteristic of T Tauri stars. Six of these objects are isolated from any known molecular cloud. Spectroscopic follow-up observations are needed to confirm the status of these objects. The results from this and future work with all-sky infrared surveys may eventually provide insight into the extent of isolated star formation and the conditions leading to star formation at high galactic latitude.
