Global Thermal Instability in the Spherical Interstellar Clouds
Mohsen Nejad-Asghar
Thermal instability (TI) is a trigger mechanism, which can explain the formation of small condensations through some regions of the interstellar clouds. The instability criterion f…
Some Aspects of Rotation and Magnetic Field Morphology in the Infrared Dark Cloud G34.43+00.24
Hamed Vahdanian, Mohsen Nejad-Asghar
The infrared dark clouds (IRDCs) are molecular clouds with relatively greater values in their magnetic field strengths. For example, the IRDC G34.43+00.24 (G34) has magnetic field…
Thermal instability through the outer half of quasi-static spherically symmetric molecular clumps and cores
Mohsen Nejad-Asghar
Thermal instability (TI) is a trigger mechanism, which can explain formation of condensations through some regions of the interstellar clouds. Our goal here is to investigate some…
The effect of magnetic field morphology on the structure of massive IRDC clumps
Nahid Bahmani, Mohsen Nejad-Asghar
Infrared dark clouds (IRDCs) have dense elongated clumps and filaments with the favorable viewing condition of being on the near-side of a bright mid-infrared background. The clump…
The Kelvin-Helmholtz instability in the Orion nebula: The effect of radiation pressure
Akram Yaghouti, Mohsen Nejad-Asghar, Shahram Abbassi
The recent observations of rippled structures on the surface of the Orion molecular cloud (Berné et al. 2010), have been attributed to the Kelvin-Helmholtz (KH) instability. The wa…
Modified Bonnor-Ebert spheres with ambipolar diffusion heating
M. Nejad-Asghar
Magnetic fluctuations through the molecular cloud cores can produce ambipolar diffusion (AD) heating, which consequently can produce temperature gradients through the core. The aim…
