项目摘要
The Sun is a touchstone for stellar astrophysics. It is an anchor for studies of the internal physics, structure and dynamics of other stars. Understanding what drives the observed changes to its activity and emissions is not only of crucial importance to solar-terrestrial relations, but also has wider relevance to studies of the influence that other stars have on their local environments, with the obvious implications for habitability of detected exoplanets. Prominent among recent solar research have been studies of the current, weak Solar Cycle 24, which has shown low levels of activity that are unprecedented in the era of modern telescope and satellite observations. As we move towards the Cycle 24/25 minimum and into the new cycle, helioseismology has an important role to play in understanding not only the internal drivers for these changes, but also how long-lasting they might be. We will track the seismic behaviour of the Sun through the decline of the current, weak activity cycle into the next solar minimum, using the Birmingham Solar-Oscillations Network (BiSON). We will mine these data and data from other ground-based and space-borne helioseismic instruments, to isolate and extract signatures of structural and dynamic changes in interior. Using our BiSON data we will also have the first ever opportunity to conduct a seismic comparison of one full 22-year Hale cycle with another. We will also utilize resolved-Sun data from satellites and the ground-based GONG network to monitor the development of near-surface flow patterns as we head into Cycle 25, and to study the internal rotation and composition of the solar envelope.Our other major focus relates to the now well established solar-abundance or solar modelling problem, i.e., the continuing disagreement of the structures of models constructed using updated chemical abundance determinations with the Sun (as determined by helioseismology). We will provide new constraints on the physics of the deep solar interior, in particular on the extent to which astrophysical opacities and non-standard physics might help to resolve the problem, exploiting the leading expertise of our consortium in modelling stellar interiors. This is an example of solar research that has important implications for the wider domain of stellar astrophysics.
太阳是恒星天体物理学的试金石。它是研究其他恒星内部物理,结构和动力学的锚点。了解驱动观察到的活动和排放的变化的因素不仅对太阳 - 物质关系至关重要,而且与其他恒星对当地环境的影响的研究更广泛,这显然对检测到的外种植体的可居住性具有明显的影响。在最近的太阳能研究中,重要的是对当前的太阳周期24的研究,该研究表明,在现代望远镜和卫星观察时代,这是史无前例的活动。随着我们朝着24/25的最低限度迈向新的周期时,Heliosesology不仅可以理解这些变化的内部驱动因素,还可以发挥重要作用,而且还可以持续多长时间。我们将使用伯明翰的太阳振荡网络(BISON),通过电流弱的活动周期降低到下一个太阳能最低限度的衰落来跟踪太阳的地震行为。我们将从其他基于地面和太空的热震仪器中挖掘这些数据和数据,以隔离和提取内部结构和动态变化的签名。使用我们的野牛数据,我们还将有第一个机会与另一个22年的Hale周期进行地震比较。我们还将利用从卫星和基于地面的锣网络中的解决的数据来监测近表面流动模式的开发,当我们进入第25周期时,并研究太阳能构造的内部旋转和组成和组成的内部旋转和组成。您的其他主要重点与现在建立的良好的无性或固体建模问题(即,使用阳光构建阳光)相关。 (由Heliosesology确定)。我们将对深太阳能内部的物理学提供新的限制,特别是在天体物理缺陷性和非标准物理学可能有助于解决问题的程度上,从而利用了我们财团在建模出色的内部室内专业方面的领先专业知识。这是太阳能研究的一个例子,对恒星天体物理学的更广泛领域具有重要意义。
