Abstract:
In this study we attempt to associate the fall meteorites that can originate from the meteor showers. Then we will characterize the Near Earth Asteroid associate parent body of the meteor shower in the context of the meteorite laboratory spectra. The list of associated objects is from Dumitru et al, A&A 2017 (publication under revision). The association method consists of two steps. Firstly, we associate the date that the meteorite has fallen with the maximum activity of the meteor shower. Secondly, the identified meteorites were compared to the spectra of the Near Earth Asteroids associated to meteor shower.We obtained seven asteroids that have spectra similarities with nine meteorites. All meteorites are ordinary chondrites, except one achondrite. Meteorites are associated with asteroids of Q, S, and X-types.
