Magneto-thermal condensation modes including the effects of charged dust particles [PDF]

open access: yes, 2009
We study thermal instability in a magnetized and partially ionized plasma with charged dust particles. Our linear analysis shows that the growth rate of the unstable modes in the presence of dust particles strongly depends on the ratio of the cooling ...
