Core properties versus feedback fraction from outflows (left), winds (centre), and supernovae (right). The rows represent the radius of the core, the velocity dispersion, the mass, and the virial parameter, respectively. The orange filled area represents the average distribution of all cores, obtained by binning over the feedback fractions to get the 25^th and 75^th percentiles. The point colours indicate the simulation time when the core is identified, as time elapsed in Myr.
