Stellar systems refer to systems composed of stars, their planets, and any other celestial bodies that orbit around them. This research area aims to study the formation, evolution, and dynamics of stars and their planetary systems, as well as the interactions between them. Researchers in this field often use observations from telescopes and spacecraft to study the properties of stars, such as their mass, luminosity, and composition. They also study the architecture of planetary systems, including the distribution of planets, their orbits, and any accompanying moons or asteroids. Stellar systems research helps scientists understand the processes that give rise to stars and planets, the factors that shape their characteristics, and how they interact with each other and the wider universe. This knowledge can provide insights into the origins of our own solar system and help us better comprehend the diversity of planetary systems throughout the galaxy and beyond.
