Fig. 8From: The relation between the surface composition anomaly and distribution of the exosphere of MercuryParameter dependence of the thermal desorption rate. The red and green lines use parameter sets adopted by Hunten and Sprague (2002) and Suzuki et al., (2020), respectively. The blue line uses parameters assumed as the most probable values by Leblanc and Johnson (2010). Each line represents the proportion of thermally desorbed Na from the surfaceBack to article page
