Photometry and models of selected main belt asteroids. VI. 160 Una, 747 Winchester, and 849 Ara

摘要

We present a set of new photometric observations of three main belt asteroids: 160Una, 747Winchester, and 849Ara. This, combined with the available data, allowed us to construct their physical models. The lightcurve inversion method was used to obtain their spins and shapes. We have resolved problems with the rotation period of 160Una, and found it to be h, almost twice the value given in the literature. Key words: techniques: photometric - minor planets, asteroids
