在3D逼真模型中“观察到”的2种骨针

2 types of spicules "observed" in 3D realistic models

Juan Martínez-Sykora

摘要:

太阳外层大气的真实三维数值模型显示了两种不同的针状现象,在太阳边缘也观察到了这种现象。数值模型采用奥斯陆交错编码(Oslo Staggered Code,OSC)三维真实模型中“观察到”的2种针状体,求解了考虑非灰场和NLTE辐射转移以及沿磁场线热传导的全MHD方程。这两种类型的针状体是模型中动力学演化的自然结果。我们讨论了这两种类型的针状体的不同性质,它们与观察到的针状体的差异以及模型中需要改进的地方。

英文摘要:

Realistic numerical 3D models of the outer solar atmosphere show two different kind of spicule-like phenomena, as also observed on the solar limb. The numerical models are calculated using the 2 types of spicules "observed" in 3D realistic models Oslo Staggered Code (OSC) to solve the full MHD equations with non-grey and NLTE radiative transfer and thermal conduction along the magnetic field lines. The two types of spicules arise as a natural result of the dynamical evolution in the models. We discuss the different properties of these two types of spicules, their differences from observed spicules and what needs to be improved in the models.
