It is demonstrated that there exists an angular momentum loss following catastrophic breakup due to asymmetric escape of fragments. This so-called angular momentum splash mechanism in catastrophic collisions is shown to cause a spindown relative to the postimpact spin rate computed without this effect. For asteroids about 100 km in diameter, there is a net spindown relative to the preimpact spin rate. The relevance of this effect to the spin evolution of asteroids of different sizes is examined.

Abstract

It is demonstrated that there exists an angular momentum loss following catastrophic breakup due to asymmetric escape of fragments. This so-called angular momentum splash mechanism in catastrophic collisions is shown to cause a spindown relative to the postimpact spin rate computed without this effect. For asteroids about 100 km in diameter, there is a net spindown relative to the preimpact spin rate. The relevance of this effect to the spin evolution of asteroids of different sizes is examined.
