论文摘要
我们使用全局磁流体动力学模拟模型通过太阳能电荷 - 交换过程检查了软X射线发射。日间磁极重新连接加热并加速等离子体，从而使X射线排放变得像$ \ sim 6 \ sim 6 \ times 10^{ - 6} { - 6} {\ rm \ ev} \ {\ rm cm cm}^{ - 3}^{ - 3} \ {\ rm s} \ rm s}^^souther incepterant incepterran。特别是，在低血浆-Yβ$太阳风条件下，我们发现X射线强度反映了重新连接区域流出的大量运动。我们建议，这种特殊的太阳风条件将允许在太阳电晕中观察到的中尺度磁磁磁性重新连接位点可视化。
We examined soft X-ray emission by the solar wind charge-exchange process around the Earth's magnetosphere using a global magnetohydrodynamic simulation model. The dayside magnetopause reconnection heats and accelerates the plasma whereby the X-ray emission becomes as bright as $\sim 6 \times 10^{-6} {\rm\ eV}\ {\rm cm}^{-3}\ {\rm s}^{-1}$ under the southward interplanetary magnetic field conditions. In particular, under low plasma-$β$ solar wind conditions, we found that the X-ray intensity reflects the bulk motion of outflows from the reconnection region. We propose that this particular solar wind condition would allow visualization of the mesoscale magnetopause reconnection site, as observed in the solar corona.
