Short summary
In this paper, we propose a new explanation for shoulder-like formations based on the test particle model. The simulation reproduced three shoulders in a substorm case. The physical explanation of shoulder formation is not yet understood. The paper suggests that the physical mechanism of shoulder formation is the result of plasma extrusion in the predawn sector, caused by the outer plasmasphere drifting radially outward and rotating faster.
