Particle dynamics: truly getting to the core of matters. Schang et al., Stewart et al., Dahoumane et al., and to an extent Ätuk et al. and Li et al. trace particles and their products through time.
RIP Arecibo- one of the gems of asteroid follow-up. Zambrano-Marin et al. give a swan song.
The Taurid Complex includes “comet” Encke (unusual in many ways), its associated meteoroid particles, and asteroids (?) with eerily similar orbits- the Encke family. When the meteoroid particles strike Earth, we see the Taurid meteor shower. But if the meteoroids cross Earth, and Encke-family asteroids have similar orbits, then what are the odds one of these asteroids can hit us too? Li et al. try to firm up the numbers.
And speaking of “comets”- “asteroid” (3200) Phaethon sheds the Geminid meteors, like a comet. Following up on Phaeton with JWST (!), Thomas et al. see what they can now see.
