Scientific paper

Photometric, spectroscopic and infrared observations are presented of 16 Hα-emission-line stars in the Gum nebula. 9 of the stars were found to be T Tauri stars. They are located in a part of the Gum nebula rich in dark clouds near the cometary globule complex CG 30 - CG 31. The globules and the associated dark clouds DC 252.9-1.6 and DC 253.1-1.7 have been mapped in the 6 cm formaldehyde line. It is concluded that they, together with the T Tauri stars and other dark clouds near the globules, define a region of star formation in the Gum nebula with preferentially low mass stars.
