Constructing a Scenario for the Formation of the Emilkowalski Family Based on Modeling the Evolution of Nominal Orbits of Asteroids

In this paper, a scenario for the formation of the young Emilkowalski asteroid family was constructed based on numerical modeling of the evolution of nominal orbits of the family members. Various variants of the orbital evolution of asteroids were considered depending on the drift velocity of the semimajor axes of the orbits, caused by the influence of the diurnal Yarkovsky effect. Using the method of analyzing the approaches of nodes and pericenters of the orbits, estimates were obtained for the time of possible formation of all possible pairs among the family members. Based on these estimates, a scenario for the formation of the family was constructed, assuming the destruction of the parent body of the asteroid (14 627) Emilkowalski as the main mechanism. It is shown that some of the family members could have formed as a result of the cascading breakup of the parent asteroid’s daughter bodies. The constructed scenario for the formation of the Emilkowalski family can be described as a step-by-step destruction of the parent body of the asteroid (14 627) Emilkowalski with elements of cascading breakup of some fragments.
