论文摘要
太阳能发电机机构在太阳内部产生的磁场驱动太阳能在一定范围的时间尺度上驱动太阳能活动。虽然仅存在几十年的太阳电晕观察结果，但存在直接的太阳突出观测，可以通过研究宇宙同位素的研究来重建太阳能开放通量和宇宙射线通量变化。尽管这种重建表明过去存在极端的太阳能活动波动，但千年尺度的发电机活动，随之而来的冠状场，太阳能开放通量和宇宙射线调制之间存在因果关系。通过使用随机强制的太阳能发电机模型，我们进行了长期模拟，以阐明发电机如何产生磁场如何控制太阳电动的结构和地球球的状态 - 如开放磁通和宇宙射线模拟电位的变化所表明的那样。我们在大型，最小和常规太阳活动阶段的太阳电晕的大规模结构的性质上建立了差异，并模拟开放的通量和宇宙射线调制电势如何随时间尺度而变化，包括太阳能活动的这些不同阶段。我们证明了模拟和重建太阳能通量的功率谱是彼此一致的。我们的研究为基于依赖宇宙同位素的重建而解释长期太阳周期变异性的理论基础，并将太阳内部变化连接到强迫Heliosphere状态。
Magnetic fields generated in the Sun's interior by the solar dynamo mechanism drive solar activity over a range of time-scales. While space-based observations of the Sun's corona exist only for few decades, direct sunspot observations exist for a few centuries, solar open flux and cosmic ray flux variations can be reconstructed through studies of cosmogenic isotopes over thousands of years. While such reconstructions indicate the presence of extreme solar activity fluctuations in the past, causal links between millennia scale dynamo activity, consequent coronal field, solar open flux and cosmic ray modulation remain elusive. By utilizing a stochastically forced solar dynamo model we perform long-term simulations to illuminate how the dynamo generated magnetic fields govern the structure of the solar corona and the state of the heliosphere -- as indicated by variations in the open flux and cosmic ray modulation potential. We establish differences in the nature of the large-scale structuring of the solar corona during grand maximum, minimum, and regular solar activity phases and simulate how the open flux and cosmic ray modulation potential varies over time scales encompassing these different phases of solar activity. We demonstrate that the power spectrum of simulated and reconstructed solar open flux are consistent with each other. Our study provides the theoretical basis for interpreting long-term solar cycle variability based on reconstructions relying on cosmogenic isotopes and connects solar internal variations to the forcing of the state of the heliosphere.
