Abstract:The ultra-low frequency instability that can be excited in a star-forming nonthermal tridust molecular cloud (TMC) is analyzed. The theoretic TMC model is composed of the Cairns-distributed tiny electrons and ions; and bipolar (hetero-polar) massive dust grains alongside partial ionization. The global quasi-neutrality condition is presumed to subsist initially in a homogeneous hydrostatic equilibrium configuration on the Jeans spatiotemporal scales. A procedural normal mode analysis over the perturbed composit… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
