The interplay between the viscosity and EUV radiation on the dispersal of protoplanetary discs

A key issue in the evolution of protostellar discs is the analysis of the mechanisms by which the disc is eventually dispersed and the time-scales involved in this process. The photoevaporation is very likely an important process in dispersing discs material and for explaining the observational time-scales needed for reaching a discless status. We analyze the role of the EUV radiation on a variety of disc models when different viscosity values are used. Our analysis focus on the changes of different diagnostic indicators commonly used for comparison of discs models and observed systems.
