Abstract From the growing observational evidence that binary / multiple star formation occurs prior to the pre-main sequence (Mathieu, 1992), it is clear that any theory of star formation MUST also explain binary formation. This paper details two formation mechanisms for binary / multiple stars, which occur simultaneously with protostar formation. The protostellar discs we form have masses 5 → 30M ⊙, diameters 200 → 4000 AU. The binaries / multiples have separations 400 → 7500 AU. The formation mechanisms were found by conducting numerical simulations of two cloud collisions, using SPH and Treecode gravity with up to 200,000 particles per calculation and a prescribed cooling equation of state.
