论文摘要
我们调查了将Sarafopoulos（2017，2019）发电机动作的主要概念应用于红色矮人和红色巨人和红色巨人和超级巨星的主要概念。因此，我们试图建立统一的发电机动作，并有可能在广泛不同的恒星领域工作。因此，产生主要的恒星磁场的强大，独特和领先的实体仍然是所谓的圆环结构。在圆环中，相同的符号电荷被相互吸引，并且可以模拟圆环作为超导体。旋转速率的现有梯度会在圆环中积累净电荷，而所得的环形电流成为磁场的驱动源。反过来，有一个复杂的二级相互作用网络影响和调节整个恒星的磁性行为。我们的发电机动作有可能在完全和部分令人信服的恒星中起作用。一个主要发现是，对于相同光谱类型的恒星，磁场的强度基本上由恒星的大小控制。我们建议，恒星越大，形成圆环的内向越深。单个圆环的形成基本上与大规模的强，poloidal和轴对称磁场拓扑结构有关，而在快速进化中产生较弱的多极，非轴对称场构型可能是由双重螺栓结构造成的（如太阳能外壳）。相同的基本概念被缩放或向下。此外，我们确定了与红色矮人，巨人和超级巨人的磁场相关的四个关键参数：首先，旋转速度；其次，剪切层旋转速率的径向梯度的陡度；第三，圆环距离光球和第四，是圆环的横截面区域。首次引入第三个关键参数。
We investigate the possibility to apply the already suggested by Sarafopoulos (2017, 2019) main concept of dynamo action to red dwarfs and red giant and supergiant stars. Thus, we attempt to establish a unified dynamo action, being potentially at work at widely varying stellar domains. Thus, the powerful, unique and leading entity generating the primary stellar magnetic field remains the so-called Torus structure. Within the Torus the same sign charges are mutually attracted and the Torus could be simulated as a superconductor. An existing gradient of the rotation rate accumulates net charge in the Torus, and the resulting toroidal current becomes the driving source of the magnetic field. In turn, there is a complicated network of secondary interactions that affect and modulate the whole star's magnetic behaviour. Our dynamo action is potentially at work in fully and partly convecting stars. A major finding is that the strength of the magnetic field, for stars of the same spectral type, is essentially controlled by the size of the star; we suggest that, the larger the star, the deeper inward the Torus is formed. The formation of a single Torus is essentially associated with a large-scale strong, poloidal and axisymmetric magnetic field topology, whereas the generation of a weaker multipolar, non-axisymmetric field configuration in rapid evolution can result from a double-Torus structure (like the solar case). The same basic concept is scaled up or down. Moreover, we identify four key parameters associated with the magnetic field of red dwarfs, giants and supergiants: First, the rotation speed; second, the steepness of the radial gradient of the rotation rate in the shear layer; third, the distance of the Torus from the photosphere and fourth, the cross-sectional area of the Torus. The third and fourth key parameters are introduced for the first time.
