Wave observations are as yet an important technique to resolve fine structures in the plasma that cannot be identified by different instruments. In this way, we proposed the generation of electrostatic solitary waves during the interaction between the solar wind particles and Venus’s atmosphere at high altitude. The plasma system is treated as a multicomponent unmagnetized plasma consists of background electrons, positive ions (H⁺ and O⁺), and streaming solar wind electrons and protons. The dispersion relation is derived for linear waves and the stability/instability of electrostatic wavepackets is investigated. The dependence of the instability growth rate on the ion beam speed has been analyzed. Stability analysis reveals the occurrence of an imaginary frequency part in three regions. Using the reductive perturbation theory, the set of fluid equations is reduced to the Korteweg-de Vries (KdV) equation to describe the evolution of small but finite amplitude soliton waves. The model predicts the propagation of electrostatic soliton waves with an electric field of 1.2 mV/m and a time duration of 0.4 ms. The output of the fast Fourier transform of the electric field pulse is a broadband in the frequency range of $~$3.2 to 199.5 kHz. It is proposed that the model can be a decent possibility for clarifying the observation of a wide variety of plasma oscillations by Galileo flyby of Venus.

波浪观测仍然是解决等离子体中精细结构的重要技术，这些精细结构无法用其他仪器来识别。通过这种方式，我们提出了在高空太阳风粒子与金星大气相互作用期间产生静电孤波的问题。等离子体系统被视为由背景电子，正离子（H ⁺和O ⁺），并流过太阳风中的电子和质子。推导了线性波的色散关系，并研究了静电波包的稳定性/不稳定性。分析了不稳定性增长速率对离子束速度的依赖性。稳定性分析揭示了在三个区域中虚部出现的情况。使用还原摄动理论，将流体方程组简化为Korteweg-de Vries（KdV）方程，以描述小而有限振幅的孤子波的演化。该模型预测电场为1.2 mV / m，持续时间为0.4 ms的静电孤子的传播。电场脉冲的快速傅立叶变换的输出是在以下频率范围内的宽带$〜$3.2至199.5 kHz 提出该模型可能是澄清金星的伽利略飞越对各种等离子体振荡的观察的一个体面的可能性。
