论文摘要
在2-5 a处动态不同的彗星和活性小行星。你。以不同程度和形式显示灰尘活动。物理参数的光度研究和比较可以帮助对此类对象的活动的机制和性质进行分类。我们使用在2012年至2016年获得的主要小行星带及周围区域中15个活性物体的宽带光度法介绍了新观察,该研究旨在比较主带彗星(MBCS),Quasi-hilda彗星(QHC)和活性小组(AAS)的物理特性。使用BVR宽带过滤器,使用乌克兰基夫彗星站的0.7米望远镜,西班牙喀尔喀尔alto天文台的1.23 m望远镜进行了观测。测量了核半径,AFRHO参数和颜色指数的上限。 2012 - 2016年观察结果表明,MBC和QHC的物理参数存在系统差异。
Dynamically different groups of comets and active asteroids with orbits at 2 - 5 a. u. show dust activity in varying degrees and forms. Photometric study and comparison of physical parameters can help to classify mechanisms and nature of the activity for such objects. We present new observations using broadband photometry of 15 active objects in the main asteroid belt and surrounding regions obtained during 2012 - 2016. The study aims to compare the physical properties of main-belt comets (MBCs), quasi-Hilda comets (QHCs), and active asteroids (AAs). The observations were carried out with the 0.7-m telescope of the Kyiv Comet Station, Ukraine, and with the 1.23-m telescope at the Calar Alto Observatory, Spain, using BVR broadband filters. Upper limits for the nuclear radii, Afrho parameters, and color indices were measured. The results of 2012 - 2016 observations suggest that there exist systematic differences in the physical parameters of MBCs and QHCs.
