论文摘要
随着白色矮人（WD）恒星凉爽，它们经过一个或多个$ g $（重力） - 模式脉冲不稳定性的阶段，成为多重变量恒星。穿过这些不稳定性领域的恒星使天文学家可以通过星空学技术研究其内部，就好像他们可以通过分析脉动时期的光谱来“看”自己的内部。 WD Asterosemology近年来经历了非凡的进步，这要归功于Kepler和Tess等太空任务提供的前所未有的质量的光度观察。在监测可变WD的过程中，这些进展伴随着开发新的恒星模型和用于建模其脉动的技术。在本文中，我们回顾了有关这些引人入胜的脉动恒星的最杰出发现，这使人们对正在进行的苔丝任务的高度敏感性和连续观察成为可能，请记住，从这个独特的太空望远镜衍生出来的近期未来可能会有更多的新结果。
As white-dwarf (WD) stars cool, they go through one or more stages of $g$(gravity)-mode pulsational instability, becoming multiperiodic variable stars. Stars passing through these instability domains allow astronomers to study their interiors through asteroseismological techniques, as if they could "look" at their interiors by analyzing the spectra of pulsation periods. WD asteroseismology has experienced extraordinary advances in recent years thanks to photometric observations of unprecedented quality delivered by space missions such as Kepler and TESS. These advances in the monitoring of variable WDs have been accompanied by the development of new stellar models and techniques for modeling their pulsations. In this article, we review the most outstanding findings -- up to early 2022 -- about these fascinating pulsating stars made possible with the high-sensitivity and continuous observations of the ongoing TESS mission, bearing in mind that there will possibly be many more new results in the immediate future derived from this unique space telescope.
