Asteroseismology and Helioseismology at Birmingham and Queen Mary

这是一个研究太阳、恒星和它们的外行星的黄金时代，特别是由于新的卫星观测的质量和范围前所未有。这些数据使得使用星震学研究大量恒星成为可能，星震学是通过观察和分析恒星的内在振荡来研究恒星的。我们对恒星（包括太阳）的理解中的重大不确定性对更广泛的天文学领域产生了直接影响，例如，校准银河系外尺度的距离，确定最古老恒星群的年龄（这对宇宙学有严格的限制），并追踪星系的化学演化。最先进的恒星研究对于完全理解系外行星系统的形成和演化也至关重要，从星震学对恒星进行的推断可以直接限制系外行星的性质（例如，大小、在可居住区域中的位置、年龄等）。恒星是宇宙可见的组成部分，而离我们最近的星星太阳对地球上的生命至关重要。负责太阳活动及其变化的内部机制位于从太阳到地球的链条的一端。太阳的可变性很难理解。太阳也扮演着一个基本的校准器的角色，并参考，为恒星结构和恒星演化理论的不同领域。因此，阐明它的结构和动力学的细节是关键，不仅在理解太阳的背景下，而且在其他恒星的背景下。这个研究计划是一个由伯明翰大学（UoB）和伦敦大学（QMUL）的玛丽女王的恒星群组成的财团。它汇集了来自UoB和QMUL的世界领先的专业知识，开展了一项星震学和日震学研究计划，该计划涵盖数据收集、数据分析和理论建模等学科，适用于太阳、太阳型和红巨星。包括新发现的系外行星系统的特性和动力学特征。该计划将利用美国宇航局开普勒使命和法国宇航局的最新数据。CoRoT卫星在对太阳的研究中，UoB将继续运行伯明翰太阳振荡网络（野牛）。我们将使用这些和其他世界领先的地震数据集来关注最近观察到的活动太阳行为的变化，这些变化将太阳带回到近100年来未见的较低活动水平。

It is a golden era for studies of the Sun, stars, and theirexoplanets, thanks in particular to new satellite observations ofunprecedented quality and scope. These data are making it possible toinvestigate large numbers of stars using asteroseismology, the studyof stars by observation and analysis of their intrinsic oscillations.Significant uncertainties in our understanding of stars (including theSun) have a direct impact on wider areas of astronomy, e.g.,calibration of distances on extra-galactic scales, fixing the ages ofthe oldest stellar populations (which place tight constraints oncosmologies), and tracing the chemical evolution ofgalaxies. State-of-the-art studies of stars are also crucial to acomplete understanding of the formation and evolution of exoplanetarysystems, and inferences made on stars from asteroseismology allowdirect constraints to be placed on exoplanet properties (e.g., sizes,locations in habitable zones, ages etc.). Stars are the visiblebuilding-blocks of the Universe and the nearest star to us, the Sun,is vital to life on Earth. The internal mechanisms responsible forsolar activity, and its variability, lie at one end of the chainstretching from the Sun to the Earth. Variability of the Sun remainspoorly understood. The Sun also plays the role of a fundamentalcalibrator, and reference, for different areas of stellar structureand stellar evolution theory. Hence, elucidating the details of itsstructure and dynamics is key, not only in the context ofunderstanding the Sun, but also other stars.This research programme is a consortium comprised of the stellargroups at the University of Birmingham (UoB) and Queen Mary,University of London (QMUL). It brings together world-leadingexpertise from UoB and QMUL in a programme of asteroseismology andhelioseismology research that spans the disciplines of datacollection, data analysis and theoretical modelling as applied to theSun and solar-type and red-giant stars, including the characterisationof the properties and dynamics of newly discovered exoplanet systemsThe programme will make use of state-of-the-art data from the NASAKepler Mission and the French-led CoRoT satellite. In studies of theSun, UoB will continue to run the Birmingham Solar-OscillationsNetwork (BiSON). We shall use these and other world-leadinghelioseismic datasets to focus on the recent observed changes inbehaviour of the active Sun, which are taking the Sun back to lowerlevels of activity not seen for almost 100 years.
