... If the temperature of the dust cloud is 10 K, then concentration of atomic gas decreases 10 times as much ,that corresponds to velocity of conversion of HI into molecular form (3 - 5) . ...
... Diffuse interstellar bands vs. rotational temperatures of simple molecular species . Presentation . Krelowski, Jacek . ... Diffuse clouds as initial conditions for chemistry in starless cores . Presentation. ...
... The observed variations may be due to "local" extinction in the central star-forming re gion, which resides in the direction of the densest cloud of neutral and molecular gas and is possibly partially embedded in it. ...
... The distribution of the axes of rotation of clouds in space is random, which leads to the conclusion that the collision of clouds is the main source of their rotation. ...
... Also, diffuse clouds play a key role in star formation. ... of its composition (dust size distribution, atomic and molecular gas) a number of unknown spectroscopic features, such as the ...
... Among others the particularity of thermodynamics connected with HD molecular cooling favoring formation of low-mass protostellar clouds, and possible negative feedback preventing formation of stellar population in primeval gas. ...
... of high mass star forming regions in various molecular lines and in millimeter wave ... Basic physical prop erties of detected clumps and molecular abundances were derived. ...
