摘要
小行星自转参数的资料不仅可以为小行星碰撞演化提供数据,还可以为太阳系的演化研究提供依据.利用云南天文台1米望远镜对主带碳类小行星(360)Carlova进行了新的CCD测光观测,结合前人的测光资料,利用Epoch-方法对(360)的自转参数进行了反演计算,得到该小行星自转的恒星周期为0.25780417±0.00000003天,自转轴的黄道坐标为(95°±3,°40°±1°).新的结果与前人的结果相比较为一致,其精度稍高于以前的估算结果.
The spin parameters of asteroids can provide important evidence for the study of asteroid's evolution, even for the evolution of solar system. The new observation for the C-type main belt asteroid (360) Carlova was performed on Nov. 15, 2000 with 1-meter telescope in Yunnan Observatory, China. Combined with other previous observations, the spin parameters of (360) were derived using the Epoch method. With a the new precise light curve obtained, the new spin parameters: sidereal period 0.25780417±0.00000003 day, and ecliptic coordinate of pole (95°± 3° , 40° ± 1° ). They have higher precision than the previous values.
