Abstract

(Abstract only) This work aims to expand our understanding of the physical characteristics of the Tina asteroid family in the main belt. This small group is unusual, as the only asteroid group currently known to be completely contained in the stable island of one of the principal secular resonances of the main belt, the n6. This family is almost near the center of the main asteroid belt, having its members with a semi-major axis between 2.765 au and 2.807 au. Its largest body is (1222) Tina, 21 km in diameter and an X-type asteroid. We aim to find their taxonomic types by performing correlations with their color indices.
