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.

这是对太阳，星星和外部行星进行研究的黄金时代，尤其要归功于新的卫星观测，其质量和范围是未来的。 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肿瘤学），并追踪galaxies的化学进化。对恒星的最新研究对于完全理解了对超球星系系统的形成和演变以及对恒星对恒星的推论以及将恒星的推论放置在系外行星特性上（例如，尺寸，可居住区域中的位置，年龄等等的位置等）至关重要。恒星是宇宙的可见构建块，而与我们最近的恒星，太阳，对地球上的生命至关重要。导致孔隙活性的内部机制及其可变性位于从太阳到地球的链式的一端。太阳的可变性是遗体理解的。太阳还扮演着基本量表的作用，并参考了恒星结构恒星进化论的不同领域。因此，阐明其结构和动态的细节是关键，不仅在理解太阳的背景下，而且在其他明星的背景下。本研究计划是由伯明翰大学（UOB）和伦敦大学（QMUL）的玛丽皇后玛丽（QMUL）组成的一个财团。 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任务和法国领导的Corot卫星。在对THESUN的研究中，UOB将继续运行伯明翰太阳能振荡Network（Bison）。我们将使用这些和其他世界领先的震中数据集专注于活跃的太阳的最新观察到的变化，这些变化将太阳带回了将近100年来未见的活动的下层活动。
