太阳黑子 Sunspot

(重定向自Sun Spots)
有时太阳黑子用肉眼即可观察到注意:需配戴护目镜才可直视太阳!
太阳黑子NOAA 875来自太阳黑子NOAA 875的闪焰

太阳黑子是太阳光球上的临时现象,它们在可见光下呈现比周围区域黑暗的斑点。它们是由高密度的磁性活动抑制了对流的激烈活动造成的,在表面形成温度降低的区域。虽然它们的温度仍然大约有3000-4500K,但是与周围5,780K的物质对比之下,使它们清楚的显视为黑点,因为黑体(光球非常近似于黑体)的热强度(I)与温度(T)的四次方成正比。如果将黑子与周围的光球隔离开来,黑子会比一个电弧更为明亮。当它们在太阳表面横越移动时,会膨胀和收缩,直径可以达到80,000公里,因此在地球上不用望远镜也可以直接看见。

激烈的磁场活动显示,太阳黑子会导致次一级的活动,像是冕圈和再联结事件。大多数的闪焰和日冕物质抛射都起源于可见到黑子群存在的磁场活动区域。相似的现象也在一些有着星斑的恒星上被直接观测到。

Sunspot 太阳黑子

(重定向自Sun Spots)

Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere. Sunspots usually appear in pairs, with pair members of opposite magnetic polarity. The number of sunspots varies according to the approximately 11-year solar cycle.
