During the stage of planetary accretion, dust grains re-emitted by planetesimal collisions could be targets of the solar wind implantation. The present study shows that such off-disk implantation can play an important role in noble gas capture; our results explain not only the ^<36>Ar amount in the Venusian atmosphere but also the fact that the ^<36>Ar abundance in Venus is 70 times as much as that in the Earth, assuming that gravitational scattering by the proto-Venus should enhance the orbital inclination of target materials. This mechanism may also have played a role in the origin of gas-rich meteorites.}, pages = {326--334}, title = {Penetration of the solar wind after dissipation of the solar nebula: Origin of Venusian Ar by off-disk implantation of the solar wind}, volume = {2}, year = {1989} }
