T Tauri stars and dust clouds in a region of the Gum Nebula

Abstract [en]

Photometric, spectroscopic and infrared observations are presented of 16 H-alpha emission-line stars in the Gum nebula.  Nine 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.
