It was determined that the connected system S1 and S2 was formed in ~3 million years. The formation of a hierarchical ternary system occurs in ~18 million years, but not for all sets of randomizations. Also, the von Zeipel-Lidov-Kozai effect was found for most of the models.  Product Description popup.authors Ishchenko Maryna V. Bertsyk Peter P. popup.nrat_date 2023-01-03 Close
