Normally, Astrophysical Journal isn’t much of a source on small bodies. The March “issue,” however, has some asteroid/comet research of note, touching upon basic laws of the Solar System:
vol. 963 Issue 1 (March 1):
Taki, T. Wakita, S. Chondrule Survivability in the Solar Nebula p. 39 ad18b7
vol. 963 Issue 2 (March 10):
Zhao, R. Li, A. Yang, B. et al. Dust and Volatiles: The Disintegrating Comet C/2019 Y4 (ATLAS) p. 90 ad1ab7
The formation of asteroids (and therefore, planetesimals… and therefore, planets… and therefore, us) from nebular condensates is not just important, it’s… EVERYTHING. In turn, the de-formation (comet death) of small bodies is one of the ways we study such astromaterial. Because comets are so difficult to examine in telescopes alone… AND difficult to orbit with spacecraft (due to highly eccentric orbits) we must turn to whatever tells us of a comet’s micro- and macro- construction.
