Notes. and are the stellar and the solar mass-loss rate (~2 × 10−14 M yr−1, Johnstone et al. 2015b), respectively. Tswp, υswp, and nswp are the temperature, velocity, and density of the fast solar wind at the orbit of the planet. ne,swp is the density of the fast solar wind scaled to the stellar mass-loss rate, also at the planetary orbit.
