Abstract / Description:In this paper we present results obtained in
the framework of a visible spectroscopic and
photometric survey of Trojan asteroids. We
concentrated on bodies orbiting at the L5
Lagrangian point of Jupiter that are also
members of dynamical families. Spectroscopy is a
crucial tool that allows us to characterize the
mineralogical composition of families and their
parent bodies, gives evidence of ongoing space
weathering, and confirms family membership. We
have observed 18 objects belonging to the Aneas,
Astyanax, Sarpedon, and Phereclos families as
defined by Beaugé and Roig (2001, Icarus 53,
391). In addition, we have determined the
spectroscopic properties of 8 background Jupiter
Trojans. The observed spectra are reddish with a
dominance of D-type asteroids. As expected, the
spectra of the non-family members are more
heterogeneous compared to the spectra of family
members, with the exception of the members of
the Aneas family. We also confirm the lack of
absorption features in the visible region, as
already reported by other authors.
