Abstract: In this work we investigate the orbital distribution of interstellar objects (ISOs), observable by the future wide-field National Science Foundation Vera C. Rubin Observatory (VRO). We generate synthetic population of ISOs and simulate their ephemerides… read more here.

Abstract: The observed near-Earth asteroid (NEA) population contains very few objects with small perihelion distances, say, $q \lesssim 0.2\, \mathrm{au}$. NEAs that currently have orbits with larger q might be hiding a past evolution during which… read more here.
