Can Warm Neutral Medium Survive Inside Molecular Clouds?
Recent high resolution numerical simulations have suggested that the interstellar atomic hydrogen clouds have a complex two-phase structure. Since molecular clouds form through the contraction of HI gas, the question arises as to whether this structure is maintained in the molecular phase or not. Here we investigate whether the warm neutral atomic hydrogen (WNM) can exist in molecular clouds. W...
متن کاملExtent of Warm and Diffuse Clouds
We present a follow-up observation on Geballe and Oka (2010, ApJ, 709, L70), who found high column densities of H+3 100 pc apart from the Galactic center on the lines of sight to 2MASS J17432173 2951430 (J1743) and 2MASS J17470898 2829561 (J1747). The wavelength coverages on these sightlines have been extended in order to observe two key transitions of H+3 — R(3, 3) l and R(2, 2) — which constr...
متن کاملRain Initiation Time in Turbulent Warm Clouds
A mean field model is presented that describes droplet growth resulting from condensation and collisions and droplet loss resulting from fallout. The model allows for an effective numerical simulation. The numerical scheme that is conservative in water mass and keeps accurate count of the number of droplets is applied, and the way in which the rain initiation time depends on different parameter...
متن کاملOrigin of CH in diffuse molecular clouds Warm H2 and ion-neutral drift
Context. Molecular clouds are known to be magnetised and to display a turbulent and complex structure where warm and cold phases are interwoven. The turbulent motions within molecular clouds transport molecules, and the presence of magnetic fields induces a relative velocity between neutrals and ions known as the ion-neutral drift (vd). These effects all together can influence the chemical evol...
