Profiles of solitary waves in case of oblique propagation (left) and quasi-parallel propagation (right), where (a) and (b) are the solitary profiles in dependence on σ_sp(= T_sp/T_e), where σ_se(= T_se/T_e) = 2. (c) and (d) are the solitary profiles in dependence on σ_se, where σ_sp = 1. The other plasma parameters are Q_O(= m_H/m_O) = 1/16, Q_sp (= m_H/m_sp) = 1, α(= n_O0/n_H0) = 3.5, β (= n_sp0/n_H0) = χ (= n_seo/n_H0) = 1.4, σ_O (= T_O/T_e) = σ_H (= T_H/T_e) = 0.2, u_sp0 = 3.3, and B₀ = 100 × 10⁻⁵ G (100 nT).
