The journal Astronomy & Astrophysics is a bit light for May (vol. 698):
Rojas, J. Duprat, J. Dartois, E. et al. Light element isotopic heterogeneities in organic residues that formed by the ion irradiation of ices A34 202451601
Kenworthy, M. A. de Mooij, E. Brandeker, A. et al. Upper limits on CN from exocomets transiting β Pictoris A10 202554073
Christou, A. A. Georgakarakos, N. Marshall-Lee, A. et al. New asteroid clusters and evidence of collisional fragmentation in the L5 Trojan cloud of Mars A42 202553804
Rojas et al. are doing experimental astronomy: trying to simulate, in the lab, processes in space to see if we have a good understanding or not. For the case of organics, bombarded by space radiation, lab work is reasonably close- no brutal pressures or temperatures or other such caveats. In effect, Rojas et al. built a mock comet, like others before them, and now competing with them.
Speaking of comets, we can now study other stars to the level of the disks around them. These circumstellar disks have, in part, formed into comets and asteroids. Of course, we can’t see individual small bodies in other systems- we are speaking in broad terms about the collective belts of bodies. Based on spectroscopy, Kenworthy et al. speak broadly of β Pictoris’ comets.
A bit more down-to-Earth: there are partial or thin “belts” of small bodies in commensurate orbits with Earth, Mars, etc. In the case of Mars (near Earth and Jupiter, with their higher masses and gravities), very few such orbits are long-term stable, and nontrivially populated. But two spots, the leading/trailing Trojan (Lagrange) points, have asteroids in them: Trojan asteroids of Mars. As our telescopes get better and better, we can spot more and more small bodies. Christou et al. have spotted such Mars Trojans; we can (they claim) start to say things about them at the level of populations and statistics.
