Star formation in BOK globules and low-mass clouds. V.H-alphaemission stars near SA 101, CG 13 and CG 22.

We have surveyed five fields in the Gum Nebula containing cometary globules, in a search for new regions of low-mass star formation. Seven H-alpha emission stars were found in association with the CG4/CG6/Sa101 cloud complex, and one in association with the CG13 globule. All eight stars are late-type emission line stars, and appear to be low-mass pre-main sequence stars. Low dispersion spectra and optical and IR photometry are presented for the objects, as well as for PH-alpha 92, an already known young star in CG22. Most of the globules surveyed are not associated with H-alpha emission stars. We demonstrate that star formation has occurred in the Gum Nebula over several million years, right up to very recently.
