[Coexistence of positive and negative polarity solitary waves] Plots of (a) Sagdeev pseudopotential, (b) associated electrostatic potential pulse (\(\phi \)) and (c) electric field (E) (bipolar pulse) profiles of ion-acoustic mode are depicted versus the space coordinate \(\eta \), for different values of V and \(\kappa \). We have considered \(\delta _b=0.01\), \(\delta _\alpha =0.055\), \(\delta _e=1.1\), \(\delta _b = 1.1\), \(U_{b0}=17.14\), \(\mu _\alpha =4\), \(Q_\alpha =2\) and \(\mu _b=1/1836\) in these plots.
