Abstract
We study dynamical effects of cosmics rays (CRs) on the thermal instability in the
linear regime. CRs and the thermal plasma are treated as two different interacting
fluids, in which CRs can diffuse along the magnetic field lines. We show that growth
rate of the magnetothermal condensation mode is reduced because of the existence of
CRs and this stabilizing effect depends on the diffusion coefficient and the ratio of the
CRs pressure to gas pressure. Thus, a slower rate of structure formation via thermal
instability is predicted when CRs are considered.
