Analysis reveals how plasma parameters affect solitary wave properties in exotic plasmas, indicating significant astrophysical implications.

The aim is to investigate the behavior of ion-acoustic solitary waves in an unmagnetized multicomponent plasma.
Employed reductive perturbation method to derive the KdV equation.
Examined the effects of various plasma parameters such as density ratios and mass ratios.
Analyzed amplitude, phase speed, and width of solitons under different conditions.
Only fast rarefactive solitons were observed in the plasma model.
Phase speed, amplitude, and width of solitons were significantly modified by plasma parameters.
Amplitude decreases with increased density ratios and increases with the relativistic factor.
