论文摘要
太阳样振荡在带有对流信封的酷星中被激发，并为限制基本恒星特性和内部物理学提供了强大的工具。我们提供了对探测太阳能振荡的简短历史，尤其是由Corot和Kepler任务开始的空间光度法革命。然后，我们讨论了从这些任务中学到的一些教训，并强调了较小的空间望远镜（例如Brite星座）的持续重要性，以表征具有独立观察性约束的非常明亮的恒星。例如，我们使用BRITE观测值来测量αCENA的初步表面旋转周期为28.3 +/- 0.5天，到目前为止，这受到了很大的约束。我们还讨论了TESS任务中太阳能振荡器的预期产量，表明TESS将通过在附近的大量子巨头中发现振荡来补充开普勒，并目前在苔丝外恒星宿主星中对振荡的首次检测。
Solar-like oscillations are excited in cool stars with convective envelopes and provide a powerful tool to constrain fundamental stellar properties and interior physics. We provide a brief history of the detection of solar-like oscillations, focusing in particular on the space-based photometry revolution started by the CoRoT and Kepler Missions. We then discuss some of the lessons learned from these missions, and highlight the continued importance of smaller space telescopes such as BRITE constellation to characterize very bright stars with independent observational constraints. As an example, we use BRITE observations to measure a tentative surface rotation period of 28.3+/-0.5 days for alpha Cen A, which has so far been poorly constrained. We also discuss the expected yields of solar-like oscillators from the TESS Mission, demonstrating that TESS will complement Kepler by discovering oscillations in a large number of nearby subgiants, and present first detections of oscillations in TESS exoplanet host stars.
