反粒化,p模式和磁性之间的相互作用?

Interactions between reversed granulation, p-modes, and magnetism?

Alfred G. de Wijn, Scott W. McIntosh, Bart De Pontieu

摘要:

我们调查的特点,观察到在Ca II H序列从日出的地方,反向造粒似乎与p-模式相互作用。这些特征在宁静的阳光下无处不在。它们与反向颗粒化是共空间的,并且显示类似的一般性质,但是具有更尖锐的边缘并且显示快速的亮度变化。它们也主要出现在宽的晶间通道上方,表明与磁性有潜在的联系。我们报告的外观和动态的这些功能,使用高分辨率,高节奏的观测日出,我们讨论了它们可能的起源。

英文摘要:

We investigate features that are observed in Ca ii H sequences from Hinode in places where reversed granulation seems to interact with p-modes. These features appear ubiquitously in the quiet sun. They are co-spatial with reversed granulation, and display similar general properties, but have sharper edges and show fast brightness changes. They also appear predominantly above wide intergranular lanes, indicating a potential connection with magnetism. We report on the appearance and dynamics of these features using high-resolution, high-cadence observations from Hinode, and we discuss their possible origin.
