论文摘要
我们检查了βHydri（G2 IV）中的声能产生和传播。这项工作的基本动机基于Beta Hydri（南半球的明星）的太阳，出色和银河系相关性，很容易被理解为未来太阳的主要例子和代理 - 因此可以评估和分析太阳能活动的世俗衰减。关于磁能产生，我们考虑纵向通量管波。我们还评估声波。对于声波能通量，β氢化氢和太阳获得的结果之间的差异明显小于主要序列恒星通常获得的差异，这在很大程度上是由于声能产生的重力依赖性。此外，我们研究了对应于不同磁通管扩展的不同磁性填充因子的磁能通量的高度依赖性行为。最后，我们评论未来研究的可能方向。
We examine the acoustic and magnetic energy generation and propagation in beta Hydri (G2 IV). The underlying motivation for this work is based on the solar, stellar, and galactic relevance of beta Hydri (a star in the Southern hemisphere), which is readily understood as a prime example and proxy of the future Sun - thus allowing assessments and analyses of the secular decay of solar activity. Regarding the magnetic energy generation, we consider longitudinal flux tube waves. We also assess acoustic waves. For the acoustic wave energy flux, the difference between the results obtained for beta Hydri and the Sun is significantly smaller than typically attained for main-sequence stars, which is largely due to the gravity-dependence of the acoustic energy generation. Furthermore, we study the height-dependent behavior of the magnetic energy flux for different magnetic filling factors corresponding to different flux tube spreadings. Finally, we comment on possible directions of future research.
