摘要

太阳系研究中心(CS3)从2019年7月至9月获得了28颗近地小行星(NEAs)的光曲线,对其自转周期、峰-峰振幅以及卫星或翻滚迹象进行了分析。2059 Baboquivari、(90403)2003 YE45 和 2016 AU130 是超宽双小行星类的候选成员。2019 年的数据使 (441987) 2010 NY65 的周期似乎明确为 4.7906 h,这推翻了以前的结果,现在这些结果已经得到更新。

NEAR-EARTH ASTEROID LIGHTCURVE ANALYSIS AT THE CENTER FOR SOLAR SYSTEM STUDIES: 2019 JULY-SEPTEMBER.

Lightcurves for 28 near-Earth asteroids (NEAs) obtained at the Center for Solar System Studies (CS3) from 2019 July to September were analyzed for rotation period, peak-to-peak amplitude, and signs of satellites or tumbling. 2059 Baboquivari, (90403) 2003 YE45, and 2016 AU130 are candidates for membership within the very wide binary asteroids class. The 2019 data led to a seemingly unambiguous period of 4.7906 h for (441987) 2010 NY65, which overturned previous results that have now been updated.
