| The identification of the first two interstellar small bodies, 1I/ʻOumuamua and 2I/Borisov, has opened a new avenue through which to contextualize our Solar System in the galactic census. While ʻOumuamua's combination of properties sets it outside of the current taxonomy, Borisov was definitively comet-like. Taking ʻOumuamua and Borisov to be representative of two underlying populations of interstellar objects, both objects can inform our knowledge of planet formation. In this presentation, I'll discuss the viability of the various compositions that have been hypothesized to reconcile ʻOumuamua's lightcurve, non-Keplerian trajectory, and the inference that similar interstellar objects must be common in the galaxy. I'll focus on two proposed exotic molecular ices, hydrogen and nitrogen, as well as CO ice. I'll conclude by discussing the future prospects for detecting and characterizing interstellar small bodies with the Vera Rubin Observatory/LSST and focused follow-up campaigns. |
