In the present study, we simulate the sputtering of Phobos’s regolith by solar wind and planetary ions for various IMF and crustal field configurations, and solar activity conditions corresponding to January to June 2015 period (F10.7 index 130). We also include ionization of the ejected neutrals by electron impact, solar photon impact, and charge exchange reactions with solar wind protons.
