Abstract
A number of new expressions for the Roche limit are derived in order to inv estigate the splitting behavior of cometary nuclei when passing close to ma ssive bodies. These expressions handle both tensile and shear failure, taki ng the radius, density, material strength, rotation period, and spin axis o rientation of the body into account. The critical period for which bodies i n free space disrupt due to the centrifugal force is also investigated, res ulting in functions depending on radius, density, and material strength.
