TL;DR: In this article, a method is presented to simulate images of a cometary dust trail in consistency with observed gas and dust production rates, which is also applicable to dust tails including neckline and antitail phenomena.

TL;DR: In this article, the authors describe the probable appearance and size of IS particle craters from initial results of experimental impacts and numerical simulation, explain how foils are being prepared and mounted for crater searching by automated acquisition of high magnification electron images, and comment on appropriate analytical techniques for preliminary examination.

TL;DR: These experiments demonstrate that photo and/or secondary electron emission from a dusty surface changes the charging mechanism of dust particles, and laid a foundation for future investigations of its role in the surface evolution of airless planetary bodies.

TL;DR: In this paper, the authors propose that collisional fragmentation produces particles in the mass range to which the Ulysses detector is sensitive, which is consistent with the aphelion distance acquired by 50-200 μm particles evolving for 10-20 kyr under Poynting-Robertson drag from an Encke type orbit.
