Role of the H channel in the primordial star formation under strong radiation field and the critical intensity for the supermassive star formation
Kazuyuki Sugimura, Carla M. Coppola, Kazuyuki Omukai +2
We investigate the role of the H_2^+ channel on H_2 molecule formation during the collapse of primordial gas clouds immersed in strong radiation fields which are assumed to have th…
Interstellar dust charging in dense molecular clouds: cosmic ray effects
Alexei Ivlev, Marco Padovani, Daniele Galli +1
The local cosmic-ray (CR) spectra are calculated for typical characteristic regions of a cold dense molecular cloud, to investigate two so far neglected mechanisms of dust charging…
Cosmic-ray propagation at small scale: a support for protostellar disc formation
Marco Padovani, Daniele Galli, Patrick Hennebelle +2
As long as magnetic fields remain frozen into the gas, the magnetic braking prevents the formation of protostellar discs. This condition is subordinate to the ionisation fraction c…
Cosmic-ray heating of molecular cloud cores
Daniele Galli, Marco Padovani
Cosmic rays are an important source of heating in the interstellar medium, in particular in dense molecular cloud cores shielded from the external ultraviolet radiation field. The…
