论文摘要

三十年前的星空学已经从其开头发展到了发现和应用的成熟领域。这种惊人的增长已通过空间光度法实现,精度$ 10-100 $ $ 10-100 $倍,比地面观测值优于地面的观测,几乎连续的光曲线在数周至几年的时间内几乎连续的光曲线,并且跨越了跨越旨在检测所有时间变化现象的大规模地面测量。新的高精度数据充满了惊喜,加深了我们对恒星物理学的理解。 $ \ bullet $此评论探讨了过去十年以来主要是由于开普勒和苔丝太空任务的光曲线的结果:大型上主序列OBAF明星,前序列明星,奇特的恒星,奇特的星星,古典脉动器,古典脉动器,白色矮人和subdwarfs和Subdwarfs和subdwarfs和Tidbilly Binary binalies binalies。 $ \ bullet $该太空任务增加了许多班级的脉动数量。 $\bullet$ Asteroseismology measures fundamental stellar parameters and stellar interior physics - mass, radius, age, metallicity, luminosity, distance, magnetic fields, interior rotation, angular momentum transfer, convective overshoot, core burning stage - supporting disparate fields such as galactic archeology, exoplanet host stars, supernovae progenitors, gamma ray and gravitational wave前体,近距离二进制恒星的起源和进化以及标准蜡烛。 $ \子弹$星是宇宙的发光示踪剂。 Asterosology显着改善了恒星结构的模型和恒星的所有推断都取决于的模型。

Asteroseismology has grown from its beginnings three decades ago to a mature field teeming with discoveries and applications. This phenomenal growth has been enabled by space photometry with precision $10-100$ times better than ground-based observations, with nearly continuous light curves for durations of weeks to years, and by large scale ground-based surveys spanning years designed to detect all time-variable phenomena. The new high precision data are full of surprises, deepening our understanding of the physics of stars. $\bullet$ This review explores asteroseismic developments from the last decade primarily as a result of light curves from the Kepler and TESS space missions for: massive upper main-sequence OBAF stars, pre-main-sequence stars, peculiar stars, classical pulsators, white dwarfs and subdwarfs, and tidally interacting close binaries. $\bullet$ The space missions have increased the numbers of pulsators in many classes by an order of magnitude. $\bullet$ Asteroseismology measures fundamental stellar parameters and stellar interior physics - mass, radius, age, metallicity, luminosity, distance, magnetic fields, interior rotation, angular momentum transfer, convective overshoot, core burning stage - supporting disparate fields such as galactic archeology, exoplanet host stars, supernovae progenitors, gamma ray and gravitational wave precursors, close binary star origins and evolution, and standard candles. $\bullet$ Stars are the luminous tracers of the universe. Asteroseismology significantly improves models of stellar structure and evolution on which all inference from stars depends.
