Query: Observable Signatures of the Ejection Speed of Interstellar Objects from
  their Birth Systems   `Oumuamua and Borisov were the first two interstellar objects confirmed in
the Solar system. The upcoming commencement of the Vera C. Rubin Observatory's
Legacy Survey of Space of Time (LSST) will enhance greatly the discovery rate
of interstellar objects. This raises the question, what can be learned from
large-number statistics of interstellar objects? Here, we show that discovery
statistics provided by LSST will allow low- and high-ejection-speed populations
to be distinguished using the velocity dispersion and angular anisotropy of
interstellar objects. These findings can be combined with physical
characterizations to yield a better understanding of planetary system origin
and nature.
