摘要：

It is proposed that the high-speed nanodust detected by the plasma wave instrument on the STEREO spacecraft could have an origin from the sungrazing comets. Trajectory calculations are performed using a simple analytical coronal magnetic field model to explore the dynamical nature of such charged nanodust in the vicinity of the solar corona. The relevance of this very near-solar source mechanism of nanodust and pickup ions to the Solar Probe Plus mission is also discussed.
