太阳色球层中p模的传播

On the propagation of p-modes into the solar chromosphere

A. G. de Wijn, S. W. McIntosh, B. De Pontieu

摘要:

我们采用层析观测的一个小区域的plage研究传播的波从太阳光球的色球层使用傅立叶相位差分析。我们的结果显示了预期的垂直传播波周期为3分钟。周期为5分钟的波,即,在声学截止周期以上,发现仅在谱斑的外围传播,并且仅在场可以合理地预期扩展的方向上传播。我们的结论是,场倾斜是至关重要的泄漏的p-模式振荡从光球到色球层。

英文摘要:

We employ tomographic observations of a small region of plage to study the propagation of waves from the solar photosphere to the chromosphere using a Fourier phase-difference analysis. Our results show the expected vertical propagation for waves with periods of 3 minutes. Waves with 5-minute periods, i.e., above the acoustic cut-off period, are found to propagate only at the periphery of the plage, and only in the direction in which the field can be reasonably expected to expand. We conclude that field inclination is critically important in the leakage of p-mode oscillations from the photosphere into the chromosphere.
