Last-minute additions had me posting Astronomy and Astrophysics for June (vol. 686) just now. What’s that about Europeans liking comets (including their meteors)?

Okay, so there are three(ish…) non-comet, non-meteor (dust/micrometeorite) papers. Spurny et al. discuss the Ribbeck meteorite. And both Fornasier et al. and Desage et al. cover Phobos, a satellite of Mars which looks like an asteroid (and may actually be an asteroid, formerly).
That brings us to Tinaut-Ruano et al. Carbonaceous asteroids (the C-complex, C-, B-, possibly D-/P-types, etc.) have flat, mostly featureless spectra in the visible/very-near-IR range. What little can we see, from what little features are in the spectra? Not too much work has been done in the UV, partly since little result has come from prior work. But since the Gaia mission was built to look at stars anyway, it covers a little bit of UV in its “blue” (shortwave) channel. And since Gaia was sweeping the sky, this results in UV data for *thousands* of objects without even trying. And don’t forget: comet nuclei, when exposed and visible, look a lot like C-/B-/D-/P-type objects. A lot, hmmm…
