A summary is presented of the physical considerations governing line formation in molecular clouds with kinetic temperatures in the range from 5 to 100 K and...
Analyse multi-echelle des champs magnetiques dans des nuages moleculaires a structures filamentaires
Together with other observational methods, visible and near infra-red polarimetry can help to understand the morphology of magnetic fields in the neighborhood...
CO /J = 2-1/ observations of southern H II regions
Maps in the CO (J = 2-1) line of the southern H II region complexes Carina Nebula and G333.6-0.2/RCW 106 are presented and discussed. Results for the Carina...
The paper presents CO and (C-13)O J = 2-1 spectra and mapping of bipolar outflows, acquired with the 12-m NRAO antenna at Kitt Peak, for the following sources...
Correlation of broad and narrow diffuse band features Evidence for molecular carriers
Spectra of early-type stars in several heavily reddened OB associations are used to study broad diffuse bands in the range from 5700 to 6300 angstroms. The...
Cosmic Amorphous Dust Model as the Origin of Anomalous Microwave Emission
We have shown that the thermal emission of the amorphous dust composed of amorphous silicate dust (a-Si) and amorphous carbon dust (a-C) provides an excellent...
Observations from a sample of six regions of star formation in the 244 GHz, J = 5-4 rotational transition of CS, together with previous results for lower...
