The Europeans are big on comets, including lab simulations of comet materials and processes. Now, we go meta: are we big on the simulations?
We suspect grain sorting has occurred on Itokawa. There is, pretty clearly, rock movement on Ryugu and Bennu. What do the boulders seen there imply?
We’re pretty sure outer Solar System bodies are covered in an organic goo- “tholins”. In that outer Solar System, methanol is stable. What chemical chain of events (plural) produces- and may, in turn, consume- this reactive organic stock?
Europeans- especially eastern Europeans- are big on meteor astronomy. Now, we go meta again: we know little on any one meteor event, but lots on the body of meteors seen so far (i. e., statistics). What are the population stats, and their error bars?
Comets again: Suzuki et al. dive deep into coma physics and optics. Does the telescopic appearance of a comet head show what we think it shows?
Meteors again: we use radar to pick up some meteors, not the same set as visible meteors. Are the radar numbers telling us what we think they do?
Many chondrites (primitive meteorites) and their chondrules contain glass: fast-frozen “rock”. Sakurai et al. try lab astronomy on synthetic, realistic glasses.
One stage of the early Solar System was young bodies, still in the presolar nebula. This implies drag, both orbital… and rotational drag. How much, and to what end?
Many chondrites of the early Solar System contained pyroxene, a primitive and thus common rock. Some of this pyroxene has been lost- but not all. If a body shows pyroxene today, Rider-Stokes et al. claim some processes and effects.
Anand et al. use chromium and its isotopes as tracers. Chromium oxide is refractory, and thus stable. What does found chromium(s) imply? They claim to know.
