摘要

Besides three conventional, nonlinear simple waves (namely, sinusoidal, sawtooth, and spicky / bipolar) measured in space plasmas, numerous extraordinary nonlinear oscillitons (i.e., amplitude-modulated solitons) have been captured by satellites in last decades. By employing a self-similar, two-fluid (electron-ion) model, we focus on the evolution from single- frequency solitary waves to multi-frequency oscillitons. It is shown that the structures can be triggered by either the charge non-neutrality auto-modulationally, or the electron inertia mutual-modulationally.
