Photo-evaporation of clumps in planetary nebulae
We study the evolution of dense neutral clumps located in the outer parts of planetary nebulae. These clumps will be photo-ionized by the ionizing radiation from the central star and change their structure in the process. The main effect of the ionization process is the setting up of a photo-evaporation flow and a shock running through the clump. Once this shock has moved through the entire clu...
متن کاملCan Photo-evaporation Trigger Planetesimal Formation?
We propose that UV radiation can stimulate the formation of planetesimals in externally-illuminated protoplanetary disks. We present a numerical model of disk evolution including vertical sedimentation and photo-evaporation by an external O or B star. As solid material grows and settles toward the disk midplane, the outer layers of the disk become dust depleted. When such a disk is exposed to U...
متن کاملThe Photo-Evaporation of Dwarf Galaxies During Reionization
During the period of reionization the Universe was filled with a cosmological background of ionizing radiation. By that time a significant fraction of the cosmic gas had already been incorporated into collapsed galactic halos with virial temperatures ∼< 10 K that were unable to cool efficiently. We show that photoionization of this gas by the fresh cosmic UV background boiled the gas out of the...
متن کاملEffluent improvement by source reduction of chemicals used in textile printing
SOURCE REDUCTION OF CHEMICALS IN TEXTILE PRINTING This is a wide-ranging subject that is now becoming of increasing importance. Allprintersare aware of thegreater pressure being placed on them by both national and local government legislation on the environment. This legislation is aimed at reducing emission from flues and controlling and monitoring the discharge of effluents. In the past the t...
