NUMERICAL SIMULATIONS OF THE FRAGMENTATION OF PHOTOEVAPORATING NONUNIFORM CLUMPS

摘要: In this paper, we present 3D gasdynamical simulations of the interaction nonuniform clumps with an external (plane-parallel) ionizing photon ux. We show that, as a consequence initial density stratication that assumed for clump, multiple condensations are produced clump is photoevaporated. also in models where peaks and valleys variability aligned ux, fragmentation more important and, adequate amplitude wavelength variability, photons can produce hollows before it completely However, do not obtain division original into smaller clumps.
