Figure 1.
Surface density mass-loss rate profile for the different photoevaporation mechanisms. The blue line shows external photoevaporation (equation 10) with |$\dot{M}_{\rm pe,ext,0}=10^{-7}\, {\rm M}_{\odot }\, {\rm yr^{-1}}$|. The red line shows X-ray-dominated internal photoevaporation (equation 6) with LX = 1030 erg s−1. The yellow line shows EUV-dominated internal photoevaporation (equation 4) with f41 = 10.
