论文摘要
现在，在带有NASA开普勒任务等太空望远镜的数千个恒星中，通常会发现红色巨星中的太阳样振荡。平行的径向速度和光度测量结果将有助于更好地理解有关太阳能振荡器振幅的物理学。然而，大多数用于空间光度法的目标恒星太微弱，无法使用光谱。 Brite星座卫星提供了独特的机会，可以通过两种彩色监测明亮的发光红色巨人的通量变化。这些目标也足够明亮，可以通过小型望远镜（例如歌曲网络）上的高分辨率光谱仪进行监测。在这些程序中，我们将首次概述我们的全面，多年的活动，利用Brite和歌曲来表征Aldebaran，Aldebaran是天空中最亮的红色巨人之一。由于可以在大距离内看到发光的红色巨人，因此这种特征良好的物体将用作银河考古学的基准恒星。
Solar-like oscillations in red-giant stars are now commonly detected in thousands of stars with space telescopes such as the NASA Kepler mission. Parallel radial velocity and photometric measurements would help to better understand the physics governing the amplitudes of solar-like oscillators. Yet, most target stars for space photometry are too faint for light-demanding ground-based spectroscopy. The BRITE Constellation satellites provide a unique opportunity of two-color monitoring of the flux variations of bright luminous red giants. Those targets are also bright enough to be monitored with high-resolution spectrographs on small telescopes, such as the SONG Network. In these proceedings, we provide a first overview of our comprehensive, multi-year campaign utilizing both BRITE and SONG to seismically characterize Aldebaran, one of the brightest red giants in the sky. Because luminous red giants can be seen at large distances, such well-characterized objects will serve as benchmark stars for galactic archeology.
