Description
On the scale of galactic disks, supernovae are likely to be the most important form of stellar feedback on the ISM. However, the environment in which the supernovae explode is likely to have been strongly modified by the action of other kinds of feedback, particularly the earlier photoionization and winds from the exploding stars.
I will present SPH simulations of a parameter space of giant molecular clouds which I have allowed to self-consistently form stars and in which I have simulated the effects of the UV radiation and winds from the O-stars that form. I will show how the degree of damage done to the clouds depends on their initial properties and discuss the consequences for the evolution of the larger-scale ISM in terms of the leakage of ionizing photons, metals, momentum and energy from the clouds.
