摘要 | The observation light curves of the main belt asteroid (469) Argentina, obtained on March 9-11 2002 and August 10-11 2004, are presented in this paper. The complex light curve of the (469) suggests that it may be in NPA rotation. Using the Fourier analysis method, some prominent spectrum values are derived individually for two subset data. Among these period values, periods of 13.00 and 8.74 h are regarded as basic components. Other derived period values can be combined linearly with these two basic period values. If the (469) is in a free-force precession mode, the motion mode will be LAM (largest-axis mode) according the ratio of precession and rotation periods. And the minimum of I (1)/I (3) (ratio of the largest and smallest principal momentum of inertial) is 3.05. Assuming an external torque releasing by a satellite forces the (469) to precess, the mass of satellite roughly is the same order as the primary's on condition that the precession and rotation periods are two basic values. At present, we cannot draw an unambiguous conclusion on (469)'s motion for sparse data, So the further observations are necessary for understanding the (469)'s tumbling motion farther. |
