Notes. (a) From van Lieshout et al. (2016). (b)Since the dust may be subject to horizontal winds on the planet that can distribute material from the substellar point to the night side (Rappaport et al. 2012). (c)The number of particles that each meta-particle represented was scaled to set the planet’s mass-loss rate to the desired value. (d) Equal to the bulk density of Mercury. (e) See footnote 4. (f) The upper-limit determined by van Werkhoven et al. (2014) is 0.7 R⊕. (g) With an additional large bin containing 0°−89°. (h) With an additional large bin containing 91°−180°.
