The blue line is the cosmic shoreline, which is drawn by eye based on Fig. 2 of Zahnle & Catling (2018). The black points are the positions of Solar System planets. The Sun’s XUV luminosity is assumed to follow the Ribas et al. (2005) model. This figure, while not as complete as Zahnle & Catling (2018), is a near exact reproduction for the planets.
