The X-ray observations show that the ejected outer material is enriched by complex atoms, especially nitrogen, cooked inside the star's nuclear furnace and dredged up onto the stellar surface.

X射线的观测表明喷发的外层物质靠复杂的原子所浓缩，特别是氮，既在恒星的内部核反应堆反应又被撒到恒星的表面。

Instead of fusion taking place in the stellar core, it fizzles towards the surface.

这时核聚变将在恒星表面发生，而不再是其在核心了。

Moreover, the turbulent stress also causes the convection the mixing action to strengthen, so elements abundance of the stellar interior and surface are all changed.

另外，湍流应力还使对流的混合作用加强，从而导致恒星内部及表面的各元素丰度都发生改变。

Magnetic activity on the stellar surface could also be caused by accretion of material onto it.

"We think that magnetic activity on or around the stellar surface creates the super-hot plasma, " Hamaguchi said.
