J/A+A/469/173 Dissipative structures of diffuse molecular gas (Hily-Blant+ 2007) ================================================================================ Dissipative structures of diffuse molecular gas. II. The translucent environment of a dense core. Hily-Blant P., Falgarone E. =2007A&A...469..173H ================================================================================ ADC_Keywords: Interstellar medium ; Radio lines; Carbon monoxide Keywords: ISM: kinematics and dynamics - ISM: structure - ISM: magnetic fields - line: profiles Description: These maps are part of a large project aimed at analyzing the small scale morphology and velocity structure of the parsec-scale environment of a low mass dense core. The Polaris field is translucent and shows no signpost of star formation, therefore allowing an analysis of a purely turbulent field prior to star formation. Our work is based on large maps made with the IRAM-30m telescope in the two lowest rotational transitions of ^12^CO and ^13^CO (1-0) with high angular (20" or 0.015pc at 115GHz) and spectral (0.055km/s) resolutions. The new data superseeds the first IRAM Key-project of Falgarone et al. (1998A&A...331..669F, Cat. ). The field is centered at 02:00:06.0-87:42:04.1 (J2000); at the estimated distance of 150pc, the size of the maps are 0.72*0.55pc^2^.
