帕克风再探：圆盘风的扩展
Parker Winds Revisited: An Extension to Disk Winds
摘要：
本文提出了一个简单的、一维的热驱动盘风动力学模型，它继承了原Parker（1958）模型的思想。我们考虑两种不同的轴对称流线几何形状：几何形状（i）通常用于运动学模型来计算合成谱，而几何形状（ii），它表现出自相似性，更接近于由许多数值模拟的盘风发现的几何形状，可能不用于此目的-尽管它很容易与现有的运动学模型。我们提出的情况下，它应该是，即几何（ii）导致跨音速风的解决方案，具有显着不同的属性。
英文摘要：
A simple, one-dimensional dynamical model of thermally driven disk winds, one in the spirit of the original Parker (1958) model, is presented. We consider two different axi-symmetric streamline geometries: geometry (i) is commonly used in kinematic models to compute synthetic spectra, while geometry (ii), which exhibits self-similarity and more closely resembles the geometry found by many numerical simulations of disk winds, is likely unused for this purpose - although it easily can be with existing kinematic models. We make the case that it should be, i.e. that geometry (ii) leads to transonic wind solutions with substantially different properties.
