And now, this month’s Monthly Notices of the Royal Astronomical Society (vol 532, #2, August 2024)… to the extent that they have months anymore, in the digital era:
Song, Z. et al. An integrated DEM code for tracing the entire regolith mass movement on asteroids
p. 1307 /stae1537
Timar, A. et al. The response of the cometary ionosphere to space weather forcing
p. 1402 /stae1556
For those ‘lucky’ asteroids graced by an exploration probe (anthropocentric, I, know) a digital elevation model (DEM) is our ‘globe’ of its 3D-shape. Landslides, and by extension gravity/disturbances vs. mechanical strength, show up as model changes. Asteroids are not passive fossils in space, and change.
The question of change extends- in time- to space weathering. For comets, the comet/weather interaction is complex due to the coma. But this is also relevant (just less) to asteroids, including active asteroids. Asteroids are (variously) not passive fossils in space.
