Determine the physical mechanism driving P/2026 N2’s activity

Determine whether the sustained or recurrent dust production of P/2026 N2 is driven by volatile sublimation, an impulsive collisional event, rotational mass shedding, or another mechanism.

Background

The observed activity before and after perihelion, approximately constant corrected aperture brightness, and comparable effective $a(0^{\circ})f\rho$ values are consistent with prolonged or recurrent dust production. However, the compact syndyne–synchrone geometry does not distinguish sustained emission from an impulsive dust release.

The paper explicitly considers water-ice sublimation, collisions, and rotational instability as possible explanations. Because the orbital location alone does not identify the dust source and the available observations do not discriminate among these alternatives, the activity mechanism remains unresolved.
