摘要
在拉脱维亚大学天文学研究所的 Baldone 天体物理观测台研究了六颗主带小行星 1999 HK1 (11411)、1995 AM1 (30968)、1999 XC136 (53454)、1999 JN6 (70055)、1999 UQ9 (86280)、2000 SU2 (93041),其地球 MOID 小于 1AU,时间跨度为 2020-2022 年。利用傅立叶序列法、伦-斯卡格尔周期图法和相位色散最小化法对所获得的光曲线数据以及小行星中心公布的 1999-2022 年期间的数据进行了分析。给出了逐步分析的计划。比较了不同天文台数据的计算结果,得出了平均加权周期。小行星的自转周期为N11411 P = 6.544 h,N30968 P = 8.330 h,N53454 P = 4.615 h,N70055 P = 74.364 h,N86280 P = 1.315 或 6.658 h,N93041 P = 30.645 h。
LIGHT CURVE ANALYSIS OF SIX MAIN BELT ASTEROIDS WITH EARTH MOID LESS THAN 1AU
Six main belt asteroids 1999 HK1 (11411), 1995 AM1 (30968), 1999 XC136 (53454), 1999 JN6 (70055), 1999 UQ9 (86280), 2000 SU2 (93041) with Earth MOID less than 1AU were studied at the Baldone Astrophysical Observatory of the Institute of Astronomy of the University of Latvia in the time span range 2020-2022. The obtained light curve data together with published Minor Planet Center data in the time range 1999-2022 were analyzed with Fourier series, Lomb-Scargle periodogram, and Phase dispersion minimization methods. A plan of analysis step by step is given. The results computed from different observatories' data are compared and mean-weighted periods are obtained. The rotation periods are for asteroids: N11411 P = 6.544 h, N30968 P = 8.330 h, N53454 P = 4.615 h, N70055 P = 74.364 h, N86280 P = 1.315 or 6.658 h and N93041 P = 30.645 h.
