CCD photometry, spin and shape models of five asteroids: 225, 360, 416, 516, and 1223

Abstract

New CCD photometric observations for 225 Henrietta (1995), 360 Carlova (1996, 1997, 1998), 416 Vaticana (1995–96, 1998), 516 Amherstia (1995, 1996), and 1223 Neckar (1995–96) carried out at five observatories are presented. New synodical periods for two asteroids (225, 1223) have been obtained. Using all available lightcurves, the spin vectors, senses of rotation, and triaxial elipsoid models of these five asteroids have been determined or refined.
