Presolar silicates are grains of dust that were formed in the atmospheres of dying stars before being incorporated into the material that formed our solar system. These grains are incredibly small, on the order of a few micrometers in size, and can contain valuable information about the conditions and processes that occurred in these ancient stellar environments. By studying presolar silicates, researchers can gain insight into the early stages of star formation, the chemical composition of dust in the interstellar medium, and the nucleosynthesis processes that occur in dying stars. This research area is important for understanding the origins of our solar system and the broader processes that shape the formation of planets and stars.
