Abstract
The history of stellar seismology suggests that observation and theory often take turns advancing our understanding. The recent tripling of the sample of pulsating white dwarfs generated by the Sloan Digital Sky Survey represents a giant leap on the observational side. The time is ripe for a comparable advance on the theoretical side. There are basically two ways we can improve our theoretical understanding of pulsating stars: we can improve the fundamental ingredients of the models, or we can explore the existing models in greater computational detail. For pulsating white dwarfs, much progress has recently been made on both fronts: models now exist that connect the interior structure to its complete evolutionary history, while a method of using parallel computers for global exploration of relatively simple models has also been developed. Future advances in theoretical white dwarf asteroseismology will emerge by combining these two approaches, yielding unprecedented insight into the physics of diffusion, nuclear burning, and mixing.
恒星地震学的历史表明,观测和理论常常轮流推进我们的理解。最近,由斯隆数字巡天(Sloan Digital Sky Survey)产生的脉动白矮星样本增加了两倍,这在观测方面是一个巨大的飞跃。在理论方面取得类似进展的时机已经成熟。基本上有两种方法可以提高我们对脉动恒星的理论理解:我们可以改进模型的基本成分,或者我们可以在更大的计算细节上探索现有的模型。对于脉动白矮星,最近在两个方面都取得了很大进展:现在存在将内部结构与其完整进化历史联系起来的模型,同时也开发了一种使用并行计算机对相对简单模型进行全球探索的方法。理论白矮星星震学的未来发展将通过结合这两种方法而出现,从而对扩散、核燃烧和混合的物理学产生前所未有的见解。
