太阳黑子光球波对太阳$p-$模源深度的依赖性

Dependence of sunspot photospheric waves on the depth of the source of solar $p-$modes

T. Felipe, E. Khomenko

摘要:

太阳黑子中的光球波以比特征波速度更快的速度径向向外移动。有人认为它们是黑子下约5 μ m处激发的$p-$模的可见图象。使用数值模拟,我们已经进行了参数化的研究所观察到的波在光球层和更高的层所产生的源位于不同的深度。观测测量结果与太阳黑子表面以下约1毫米和5毫米之间驱动的波是一致的。

英文摘要:

Photospheric waves in sunspots moving radially outwards at speeds faster than the characteristic wave velocities have been recently detected. It has been suggested that they are the visual pattern of $p-$modes excited around 5 Mm beneath the sunspot. Using numerical simulations, we have performed a parametric study of the waves observed at the photosphere and higher layers produced by sources located at different depths. The observational measurements are consistent with waves driven between approximately 1 Mm and 5 Mm below the sunspot surface.
