We present here a list of 25 bright stars (G < 8) that are possible members of Gaia-Enceladus, a system that merged with the Milky Way approximately 10 Gyr ago, and whose debris dominates the halo near the Sun. These stars were therefore born beyond the edges of the Milky Way and are visible with binoculars. We expect the list to be of interest for public outreach and amateur astronomers. These bright stars are also useful as standard stars for calibration and validation of analysis since very high-quality spectra can be obtained with reasonable amount of telescope time.

古代合并Gaia-Enceladus的明亮星星可见双筒望远镜

我们在这里列出了25个明亮的恒星(G  <8),它们可能是盖亚-土卫二的一个成员,该系统大约在10年前就与银河系合并,其碎片占太阳附近光环的主导地位。因此,这些恒星诞生于银河系的边缘之外,并用双筒望远镜可见。我们希望该清单将引起公众宣传和业余天文学家的关注。这些明亮的恒星也可用作标准恒星,用于校准和分析验证,因为可以通过合理的望远镜时间获得非常高质量的光谱。
