Asteroseismology has significantly advanced the field of Galactic archeology, providing essential insights into the formation and evolution of our Galaxy. Here we present an asteroseismic analysis of 103 luminous red giant stars that were observed by Gaia in our Galaxy and the Large Magellanic Cloud. Leveraging a period–luminosity–amplitude relationship determined using data from the OGLE mission, we measure distances to these stars of up to 100 kpc, probing distances more than a factor of 2 beyond where Gaia parallaxes can be measured accurately. We have determined distance uncertainties of 8% or better for 80% of the stars in our sample and reduced known distance uncertainties for stars in this sample by more than a factor of 2 on average. Applying this approach to future Gaia data releases can provide more precise and accurate distances and constrain fundamental properties for 10,000+ stars across our Galaxy.

Gaia DR3 光度测量中的发光红巨星振荡的银河考古学

星震学极大地推进了银河考古学领域的发展，为我们银河系的形成和演化提供了重要的见解。在这里，我们对盖亚在银河系和大麦哲伦星云中观测到的 103 颗发光红巨星进行了星震分析。利用 OGLE 任务数据确定的周期-光度-振幅关系，我们测量到这些恒星的距离高达 100 kpc，探测距离超出了可以准确测量盖亚视差的两倍以上。我们已经确定样本中 80% 的恒星的距离不确定性为 8% 或更好，并将该样本中恒星的已知距离不确定性平均降低了 2 倍以上。将这种方法应用于未来的盖亚数据发布可以提供更精确和准确的距离，并限制银河系中 10,000 多颗恒星的基本属性。
