Scientific paper

We carried out a12CO survey of molecular clouds in the region of the reflection nebula IC 2118. Our observations covered the whole area of IC 2118 (~ 6 deg2) with a 2'.6 beam at a 4' grid spacing. We identified six molecular clouds. Based on a literature search we found a distance value of 210 pc for the reflection nebula and its associated molecular clouds, indicating that the clouds are probably interacting with the Orion--Eridanus Bubble. Using this distance value, we determined the physical properties of the clouds. We also made an objective prism search for Hα emission stars in the region in order to find possible solar-type stars born in the clouds, and identified 46 candidate pre-main-sequence stars. Their spectroscopic follow-up is in progress. Seven of them have so far proved to be T Tauri stars.
