标题： Steady-State Solutions for a Geometrically Thin Accretion Disk with Magnetically-Driven Winds

摘要： 我们提出了一维磁驱动吸积盘风模型的稳态解，该模型基于磁流体动力学方程。 我们假设一个几何薄、气体压强主导的吸积盘，结合了由扩展的alpha粘性方案引入的磁制动和湍流粘性。 此外，垂直应力参数假设与盘的高宽比成比例。 我们确认，当没有风时，推导出的解会产生标准盘解。 我们发现，当盘质量向内落时，质量吸积率会减少，而质量损失率则随半径增加。 从磁驱动盘风发出的盘谱可以被观测到，而不会受到风介质的干扰，因为风的光学厚度显著较低。 在没有风的情况下，光谱光度与中间多色黑体波段中的$\nu^{1/3}$成正比，这符合标准盘理论的预测。 然而，在有风的情况下，它在同一范围内对频率的依赖关系遵循不同的幂律。 光谱斜率偏离$1/3$，特别是出现负的光谱斜率，是磁驱动风存在的明显指示。 我们还讨论了一种观测策略，以通过多波长观测来测试我们的模型。 显示英文摘要

摘要： We present steady-state solutions for a one-dimensional, magnetically-driven accretion disk wind model based on magnetohydrodynamic equations. We assume a geometrically thin, gas-pressure-dominated accretion disk, incorporating both magnetic braking and turbulent viscosity introduced by an extended alpha-viscosity prescription. Additionally, the vertical stress parameter is assumed to scale with the disk aspect ratio. We confirm that the derived solutions result in standard disk solutions when the wind is absent. We find that the mass accretion rate decreases as the disk mass falls inward, while the mass loss rate increases with radius. The disk spectrum emitted from the magnetically-driven disk wind can be observed without interference from the wind medium because the wind is significantly optically thin. The spectral luminosity is proportional to $\nu^{1/3}$ in the intermediate, multicolor-blackbody wavebands, in the absence of wind, as predicted by standard disk theory. However, in the presence of wind, it follows a different power-law dependence on frequency over the same range. A deviation from the spectral slope of $1/3$, particularly a negative spectral slope, is a clear indicator of the presence of a magnetically driven wind. We also discuss an observational strategy to test our model with multi-wavelength observations.
