Bok globules in the Large Magellanic Cloud.


Abstract (from CDS):

We report the discovery of small, isolated dust clouds in the Large Magellanic Cloud (LMC) that are excellent candidates for counterparts to the Bok globules observed in the Galaxy. We detect these small clouds silhouetted against diffuse Hα emission on the basis of parallel imaging with the Wide Field Planetary Camera 2 on the Hubble Space Telescope. The clouds we identify as Bok globule candidates have typical sizes of approximately 1", corresponding to a linear diameter of about 0.25 pc at the distance of the LMC. We derive lower limits for the optical depth within the dark clouds and masses, assuming that the clouds have density distributions similar to Galactic Bok globules. The sizes and estimated masses for LMC globules are comparable to those estimated for Galactic globules. An extended sample of such objects would be excellent targets for high-resolution infrared and millimeter observations to study low-mass star formation in such clouds in low-metallicity environments where the distance is well known.
