Table of Contents
GSE stands for Gaia Sausage Enceladus, which is an ancient part of our Milky Way galaxy. It is made up of stars that are low in metal content and are thought to have come from a smaller galaxy that merged with the Milky Way a long time ago.
Discovery and Importance
Astronomers have found many stars in the GSE. By studying these stars, they can learn more about how the Milky Way formed and evolved. GSE is important because it provides clues about the history of star formation in our galaxy.
Star Formation History
GSE shows a long history of star formation that stopped around 10 billion years ago. This is interesting because it helps scientists understand when different parts of the Milky Way came together.
Chemical Composition
The stars in GSE have unique chemical properties, which tell us about the processes that created them. By analyzing these properties, researchers can compare GSE with other groups of stars and gather more information about the Milky Way's development.
Overall, GSE is a key piece of the puzzle in understanding our galaxy's past.
