Abstract

We have found three new members of the Rampo asteroids family: 2009HD95, 2010VO19, 2013JF69. We estimated the Yarkovsky semimajor axis drift rate. Based on the simulation results, estimates of the asteroid pairs’ age included in the family are obtained. In the scenario of the cascade disruption of the parent body of the asteroid (10321) Rampo, one can note the concentration of estimates of the pairs’ age to values of 900, 750, 500, and 250 kyr.
