Abstract

A method has been developed for analytical determination of the conditions of long-term retention in the Earth’s vicinity and the areas of spatial localization of artificial nanoparticles with sizes of the order of 10 nm, which are the products of degradation of the surface material of a large orbital object (a so-called “parent body” (PB)) moving in the Earth’s magnetosphere along a high circular orbit. The method is based on the construction of so-called “allowed” regions of motion of nanoparticles separating from the PB surface at different points of its orbit using the generalized Störmer method. Using this method, the possibility of capturing aluminum oxide nanoparticles with a radius of ~10 nm by the Earth’s magnetic-gravity trap under conditions of average geomagnetic activity was shown in the case of their insertion into near-Earth space on circular orbits with heights from ~50 000 to ~60 000 km and small inclination angles to the equatorial plane.
