The chemical traces in the atmosphere of stars is useful for uncovering the information regarding galaxy. It is known as Gaia Sausage, present in a major collision with Milky Way.

Astrophysicists, the University of Birmingham in association with colleagues at European institutions in Aarhus studies the chemical composition of stars.

Although, Gaia Sausage is recognizing the international team by using the information of Gaia Satellite from the European Space Agency. However, the merger with Milky Way is contributing to the shape of Milky Way.

Gaia Sausage

By utilizing the information regarding chemical traces of Gaia Sausage stars are coming from the APOGEE astronomical survey. However, the scientists of Birmingham are pinpointing the age of the galaxy. Hence, on developing the model of production, the nucleosynthesis of chemical elements of stars in the cosmos is estimating the Sausage formation.

Thus, the school of Physics & Astronomy, University of Birmingham, Fiorenzo Vincenzo are mentioning about the interaction of elements with light in several ways. It also helps in studying the light properties from stars inferring chemical make-up of stars.

As chemical elements are substantial than helium producing by stars through thermonuclear burning deep in the heart of a star. Several chemical elements are synthesizing various types of stars in the cosmos. Hence, oxygen atoms are significant for life processes, because of, deposition in the interstellar medium by generations of enormous stars. This helps in measuring the proportion of chemical traces in the atmosphere of stars. And use the measurement for determining the age.

On calculating the stars’ ages precisely is critical process and technique by using the Birmingham team are offering the piece of the puzzle. However, the next step will cross-reference chemical data from other techniques like studying the relative speeds of stars moving.

However, the mergers in two galaxies are producing other effects. Whereas, the team is observing a gap in the age distribution of stars in Milky Way occurring as a merger. This suggests that collision is causing a disruption in star formation in Milky Way.

Dr. Vincenzo mentions that heating and turbulence is instigating by the merger of Gaia Sausage with Milky Way preventing the star formation. Hence, for confirming if there is a need for precise measurement of ages of stars in smaller galaxy and Milky Way.
