Talk abstract

Observations of massive star forming regions show filamentary structures, bubbles and pillars that are often hailed as examples of ionisation feedback. Recent numerical simulations have achieved some success in reproducing some of the observed features, however the efficacy of the feedback mechanism is still under debate. Moreover, current star formation simulations necessarily employ a number of simplifying assumption in the solution of the radiative transfer and photoionisation problem which may limit the relevance of the results. In this talk I will examine the consequence of some of the most common approximations used and show the results of our ungoing efforts to a more holistic approach to include RT and photoionisation in the context of large scale hydrodynamical simulations.
