Bright Stars from the Ancient Merger Gaia-Enceladus Visible with Binoculars
Abstract
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.
