摘要

In this paper we present lightcurves and physical parameters for nine near-Earth objects (NEOs) (433 Eros, 1917 Cuyo, 2368 Beltrovata, 3753 Cruithne, 4769 Castalia, 4953 1990 MU, 6491 1991 OA, 1995 EK1, and 1995 FJ) and three Mars crossers (5738 Billpickering, 7467 1989 WQ1, and 10578 1995 LH) observed during six campaigns in 1992 and 1995. The photometric lightcurve observations discussed here are part of an ongoing observational follow-up program (S. Mottola et al. 1995, Icarus117, 62–70; P. Pravec et al. 1997, Icarus130, 275–286). The purpose of this program is to determine important physical parameters (rotational period and state, spin vectors, colors, and shapes) for NEOs.
