Definition

The ratio of fragment cross-sectional area to mass, a key parameter determining the magnitude of solar radiation pressure perturbation, and one of the core outputs of the break-up model. In the paper, fragment area-to-mass ratio distributions span several orders of magnitude.

Application Value

A key parameter determining solar radiation pressure perturbation magnitude. Fragment area-to-mass ratio distributions spanning several orders of magnitude make debris orbit prediction challenging.
