Photometry of the nebulae LDN1780, LDN1642 and LBN406 is used to derive scattering properties of dust and to investigate the presence of UV fluorescence emission by molecular hydrogen and the extended red emission (ERE). We used multi-wavelength opti

We have studied the ratio of 13 CO and C 18 O column densities to the extinction A J of background field stars in the direction of three globules: B 133, B 335, L 466. Selected positions in the globules were observed in the 12 CO($J=1-0$) line and in

We have studied the radial variation of the CO abundance in the nearby isolated globule Barnard 68 (B68). For this purpose, B68 was mapped in the three rotational lines 13 CO(J= 1-0), C 18 O(J= 1-0) and C 18 O(J= 2-1). Using the recent discovery of A

Cometary globule (CG) 1 and CG 2 are "classic" CGs in the Gum Nebula. They have compact heads and long dusty tails that point away from the centre of the Gum Nebula. We study the structure of CG 1 and CG 2 and the star formation in them to find clues

We have used the IRAS Point Source Catalog to select circumstellar SiO maser objects solely according to their IR properties in the catalog and to acquire a large and uniform database. The power of the point source catalog in selecting the maser cand

CO, J=3→2, J=2→l and J=1→0 observations of the extended molecular outflow in the high latitude cloud L 1228 are presented. The 12CO, J=3→2 and J=2→1 observations reveal a well collimated and extended outflow. The 12CO, J=l→0 observations
