Orbital distribution of TRS asteroids vs meteoroids

Ascertain whether the differing dynamical processes acting on asteroids compared to sub-meter-sized meteoroids within the Taurid Resonant Swarm produce substantially different orbital outcomes relative to the meteoroid-based distribution inferred from observed fireballs and meteors, and determine whether such differences would alter constraints derived from TRS simulations used to guide searches for asteroid-sized objects.

Background

Population constraints for TRS asteroids in this paper rely on simulations guided by the observed distribution of fireballs and meteors, implicitly assuming that asteroid-sized objects share similar orbital characteristics. However, asteroids and meteoroids experience different dynamical processes (e.g., nongravitational forces, collisional histories), which could lead to distinct orbital distributions.

Clarifying whether these dynamical differences lead to substantially different orbital outcomes for TRS asteroids is critical, because any divergence from the meteoroid-based distribution could affect derived upper limits and impact-risk estimates.
