Star formation around the HII region Sh2-235
M. S. Kirsanova, A. M. Sobolev, M. Thomasson +3
We present a picture of star formation around the HII region Sh2-235 (S235) based upon data on the spatial distribution of young stellar clusters and the distribution and kinematic…
Chemical differentiation in regions of high-mass star formation I. CS, dust and N2H^+ in southern sources
L. Pirogov, I. Zinchenko, P. Caselli +1
Aims. Our goals are to compare the CS, N2H+ and dust distributions in a representative sample of high-mass star forming dense cores and to determine the physical and chemical prope…
Low-mass star formation in Lynds 1333
M. Kun, S. Nikolic, L. E. B. Johansson +2
Medium-resolution optical spectroscopy of the candidate YSOs associated with the small, nearby molecular cloud Lynds~1333 revealed four previously unknown classical T Tauri stars,…
Physical and chemical structure of dense cores in regions of high mass star formation
Igor Zinchenko, Lev Pirogov, Paola Caselli +3
We found that in regions of high mass star formation the CS emission correlates well with the dust continuum emission and is therefore a good tracer of the total mass while the N$_…
The IC2118 association: new T Tauri stars in high-latitude molecular clouds
M. Kun, T. Prusti, S. Nikoli'c +2
We identified new pre-main sequence stars in the region of high-latitude molecular clouds associated with the reflection nebula IC2118, around l = 208 degr and b = -27 degr. The st…
N2H+(1-0) survey of massive molecular cloud cores
L. Pirogov, I. Zinchenko, P. Caselli +2
We present the results of N2H+(1-0) observations of 35 dense molecular cloud cores from the northern and southern hemispheres where massive stars and star clusters are formed. Line…
