摘要

在很大程度上,基于地面和现在基于空间的对一系列恒星家族的研究(所有这些都在本次研讨会上有代表)已经从对脉动本身的研究转向了对恒星物理学及其应用具有真正价值的信息。这需要改进观测和开放的恒星模型的结合,这种结合一直持续到今天。脉动致密恒星就是一个很好的例子。从20世纪80年代中期到90年代中期,一系列的观测和理论活动开始意识到这种潜力。新一代的恒星模型,再加上对地震数据的重新分析和许多新的微弱脉冲星的发现,最近使这一领域焕发了活力,并可能很快为后agb演化的一些突出问题提供确凿的答案。脉动sdB恒星的发现和分析是一个加速发展的过程,在观测基础不断发展的同时,理论模型框架也基本成熟。

Asteroseismology: Lessons From the Past and Prospects for the Future
Ground-based, and now space-based, studies of a range of stellar families (all represented at this workshop) have, in large part, moved from study of pulsations for their own sake on to information of real value for stellar physics and its applications. This required a combination of improved observations, and open-minded stellar modelling, that continues today. Pulsating compact stars provide a good example of this progress. A flurry of activity from the mid 1980s to the mid 1990s, both observational and theoretical, began to realize this potential. A new generation of stellar models, coupled with reanalysis of seismological data and discovery of many new faint pulsators, have recently revitalized this field and may soon provide firm answers to some of the outstanding problems of post-AGB evolution. The discovery and analysis of pulsating sdB stars has followed an accelerated trajectory, enjoying mature theoretical model framework largely in place at the same time as the developing observational base.
