论文摘要
帕克在太阳表面附近的稳定太阳能解决方案的稳定性通过为此解决方案提出Sturm-Liouville问题来系统地研究。帕克的太阳风解决方案，无论是微风还是超音速，取决于星际介质中的压力，都显示出可描述太阳风以稳定的方式启动，因为它从一个静止状态下离开太阳能表面：与太阳的静止，慢速运动，慢速运动。然后放松帕克太阳风模型中的等温气流假设，并将更现实的正压液和糖尿病模型用于气流。太阳风流的稳定性是从太阳表面的静止状态开始的，被证明是继续保持的。因此，帕克的太阳风解决方案似乎是该动态系统的稳定吸引子。
Stability of Parker's steady solar wind solution near the solar surface is systematically investigated by posing a Sturm-Liouville problem for this solution. Parker's solar wind solution, whether it turns into a breeze or a supersonic wind depending on the pressure in the interstellar medium, is shown to describe the solar wind to start in a stable way as it leaves the solar surface from a state of: rest, co-rotation with the Sun, slow motion. The isothermal gas flow assumption in Parker's solar wind model is then relaxed, and more realistic barotropic fluid and diabatic models are used for the gas flow. The stability of the solar wind flow, as it starts from a state of rest at the solar surface, is shown to continue to hold. Parker's solar wind solution therefore appears to be a stable attractor of this dynamical system.
