论文摘要
我们在X射线驱动的欧文和合作者的X射线驱动的光蒸发风模型中，以及Wang等人最近的磁化磁化模型中，使用多云来重新检查[OI] 6300 A和[OI] 5577 A。我们发现，在测得的积聚发光度下，FUV辐射将填充氧原子的上层，最终将有助于[OI]线。 FUV泵送与碰撞作为[OI]线的激发机制竞争，它们每个源自原始磁盘环境中的不同区域，具体取决于模拟基于的流体动力学模型的细节。因此，[OI] 6300 A和[OI] 5577 A的线强度和形状将受到辐射传输模拟中的FUV泵送的影响。
We use Cloudy to re-examine excitation of [Oi] 6300 A and [Oi] 5577 A in the X-ray driven photo-evaporative wind models of Owen and collaborators, and in more recent magnetothermal models by Wang et al. We find that, at the measured accretion luminosities, the FUV radiation would populate the upper levels of the oxygen atom which would eventually contribute to the [Oi] lines. FUV pumping competes with collisions as an excitation mechanism of the [Oi] lines, and they each originate from a distinct region in the protostellar disk environment depending on the specifics of the hydrodynamical model that the simulation was based on. Consequently, the line strengths and shapes of [Oi] 6300 A and[Oi] 5577 A would be affected by the inclusion of FUV pumping in the radiation transport simulations.
