Many models in which the object under study loses all its mass have appeared in the literature. One can find from evaporating stars to incipient black holes, all the way to evaporating black holes. In this article we try a semiclassical study of these evaporating models centered on the evaporating event itself. We analyze their common properties, behaviours and possibilities. Specifically, we pay special attention to the evaporating models as a means of avoiding singularities during the collapse. In case of any pre-existing non-spacelike curvature singularity, we show that these models tend to evaporate it. Finally, we introduce a new class of evaporating black holes.
