Numerical N-body simulations are made to understand a formation mechanism for the clumpy irregular starburst galaxy Markarian 297. A coplanar radial penetration collision between two disk galaxies explains overall morphological properties of Markarian 297. The evolutionary phase corresponds to about 150 million yr after the impact. The morphology of the disturbed galaxy looks like a 'wing'. In the case that the colliding partner is deformed to a 'ring' galaxy, the projected image of the two galaxies is quite similar to the entire observed shape of Markarian 297, when the colliding system is observed from a nearly edge-on view. It is also shown that the observed velocity field is well reproduced by this model. Numerical simulations of the gas cloud system are also made to study the star-forming activity in the galaxy. The unusually high star-formation rate (SFR) of Markarian 297, indicated by FIR observations, is explained as a sum of SFRs of both the wing and the ring galaxies.
