Search for new members and age estimation of the young Emilkowalski asteroid family

Abstract We have searched for new members of the young Emilkowalski asteroid family. The number of family members reached 13. We determined proper synthetic orbital elements of family members using Orbit9 software. We investigated the dynamical evolution of the young Emilkowalski asteroid family over a 5 Myr with Orbit9 software. To estimate the ages of the pairs, we used the method of simultaneous convergence of the nodes and perihelion orbits. We considered all possible pairs between asteroids of the family. In the case of the zero-drift rate of the semi-major axis due to the influence of the Yarkovsky effect, the ages of the pairs do not exceed 2 Myr. The obtained estimates of the age of pairs allow us to limit the integration interval in the study of the probabilistic evolution of asteroid family orbits to the range of 2 Myr.
