Parametric instability in dark molecular clouds
Received ; accepted – 2 – ABSTRACT The present work investigates the parametric instability of parallel propagating circularly polarized Alfvén (pump) waves in a weakly ionized molecular cloud. It is shown that the relative drift between the plasma particles gives rise to the Hall effect resulting in the modified pump wave characteristics. Although the linearized fluid equations with periodic c...
متن کامل33.8 GHz CCS Survey of Molecular Cores in Dark Clouds
We have conducted a survey of the CCS JN = 32 − 21 line toward 11 dark clouds and star-forming regions at 30 spatial resolution and 0.054 km s velocity resolution. CCS was only detected in quiescent clouds, not in active star-forming regions. The CCS distribution shows remarkable clumpy structure, and 25 clumps are identified in 7 clouds. Seven clumps with extremely narrow nonthermal linewidths...
متن کاملHalo Dark Clusters of Brown Dwarfs and Molecular Clouds
The observations of microlensing events in the Large Magellanic Cloud suggest that a sizable fraction (∼ 50%) of the galactic halo is in the form of MACHOs (Massive Astrophysical Compact Halo Objects) with an average mass ∼ 0.27M⊙, assuming a standard spherical halo model. We describe a scenario in which dark clusters of MACHOs and cold molecular clouds (mainly of H2) naturally form in the halo...
متن کاملPolytropes: Implications for Molecular Clouds and Dark Matter
Molecular clouds are supported against their own self-gravity by several different sources of pressure: thermal pressure, mean magnetic pressure, and turbulent pressure. Multi-pressure polytropes, in which each of these pressures is proportional to a power of the density, can account for many of the observed properties of molecular clouds. The agreement with observation can be improved with com...
متن کاملAmmonia in Infrared Dark Clouds
Context. While low mass clouds have been relatively well studied, our picture of high-mass star formation remains unclear. Infrared Dark Clouds appear to be the long sought population of cold and dense aggregations with the potential of harbouring the earliest stages of massive star formation. Up to now there has been no systematic study on the temperature distribution, velocity fields, chemica...
