A spectroscopic study of the Themis family

We present spectroscopic observations of 36 asteroids, members of the Themis family. These observations were carried on at the European Southern Observatory in the wavelength range $4900 - 9200$ Å. Most of the objects present a spectra similar to C-type asteroids and some of them present indicative...

Zusammenfassung:We present spectroscopic observations of 36 asteroids, members of the Themis family. These observations were carried on at the European Southern Observatory in the wavelength range $4900 - 9200$ Å. Most of the objects present a spectra similar to C-type asteroids and some of them present indicative of aqueous alteration. We discuss the implications of these results on the formation and evolution of this family.
