内容記述 | We have investigated the Local-Time (LT) dependence of distribution of Mercury's sodium exosphere, in order to understand production and loss processes of low release velocity component of the exosphere. As a method of the investigation, we compare a model sodium exosphere simulated from the Monte Carlo method with observation results [Sprague et al., 1997]. As an initial step of this investigation, we adopted the photon-stimulated desorption process as the release mechanism, because released sodium atoms by the process are expected to be have low-velocity and the dominant component in the dayside atmosphere near Mercury's surface [McGrath et al., 1986]. Moreover, we assumed that amount of sodium atoms supplied to Mercury's surface always exceeds that of released atoms from the surface. As the result of the comparison the model could not meet with the observed LT dependence. It is suggested that, therefore, some additional mechanism or effect, especially with the relation to balance of supply and release of sodium atoms, should be considered. | |||||
