“…Among the 15 IDPs studied in Maupin et al (2020), eight have been used in the present work. The seven others have not been used because one of them was returned to NASA (W7068C2), W7068C40 had no infrared signatures, L2076C29 was lost during transfer, and the others were impossible to extract from silicon oil despite several washes with hexane.…”

“…The collection spot is adjusted to the particle size, and by performing 20 successive rotations of 18°each, we ensure an illumination of the whole particle surface. We thus averaged the 20 spectra to obtain the reflectance spectrum of an isolated particle (see Maupin et al 2020 for more details).…”

“…Few studies have investigated the Vis-NIR reflectance spectroscopy of IDPs due to their small size (Bradley et al 1996 andMaupin et al 2020). By coupling reflectance studies with other analytical techniques, it is possible to investigate possible links between chemical composition and Vis-NIR spectral properties on direct analogs of solar system dark surfaces.…”

Primitive extraterrestrial materials are generally dark, a characteristic often associated with the presence of polyaromatic organic material and/or sulfides. We show in this study that the reflectance level measured at 0.55 μm of IDPs and some meteorites is correlated to the degree of graphitization of the polyaromatic organic matter. The reflectance level of the primitive surfaces therefore allows us to obtain information on the polyaromatic organic material present on the surface of solar system small bodies observed by remote sensing or visited by space missions. We discuss our results in view of the sample return missions Hayabusa2 and OSIRIS-REx.

The source regions of ordinary chondrites (sim 80<!PCT!> of all falls) and large S-type near-Earth objects (NEOs; sim 30<!PCT!>) have recently been identified with three young asteroid families (Karin, Koronis, Massalia) being at the origin of most ordinary chondrite falls. The present work is a continuation of our previous studies and aims to determine the source regions of the remaining meteorite and NEO classes, with an emphasis on carbonaceous chondrites (CM, CI, CO, CV, CK, CR, CH, CB, or C-ungrouped). We studied 38 individual asteroid families, including young and old ones, and determined their contributions to the NEO populations at metre and kilometre sizes using collisional and orbital models. Our models are in agreement with spectroscopic observations of NEOs, cosmic-ray exposure ages of meteorites, statistics of bolides, infrared emission from dust bands, composition of interplanetary dust particles (IDPs), and abundance of extraterrestrial helium-3. We identified the Veritas, Polana, and Eos families as the primary sources of CM/CR, CI, and CO/CV/CK chondrites, respectively. Substantial contributions are also expected from CM-like K\"onig and CI-like Clarissa, Misa, and Hoffmeister families. The source regions of kilometre-sized bodies are generally different. The Adeona family is by far the main source of CM-like NEOs, whereas the Polana (low-i) and Euphrosyne (high-i) families are at the origin of most CI-like NEOs. The Polana family is the likely source of both Ryugu and Bennu. We were able to link spectroscopically and dynamically several NEOs to the Baptistina family. Finally, it appears that the pre-atmospheric flux of carbonaceous chondrites at metre sizes is about the same as that of ordinary chondrites. Given the difference in fall statistics between the two groups (80<!PCT!> versus 4.4<!PCT!>), this implies either substantial atmospheric fragmentation of carbonaceous bodies at the level of sim MPa $ or destruction by thermal cracking and water desorption. The source regions of most meteorites and kilometre-sized NEOs have now been determined, including some minor classes such as enstatite chondrites and achondrites (Nysa, Hungaria), acapulcoites and lodranites (Iannini). Future work should focus on the few remaining classes (essentially, iron meteorites, pallasites, and ureilites).
