Harshitha G submitted a seminar topic on "The Sun" to her faculty member Sandheep D H. The seminar discussed astrophysics as the study of physical and chemical processes in stars and galaxies, and covered information about the sun such as its composition of hydrogen, helium and other gases, and location at the center of the solar system. It also defined a star as an object that produces its own energy through heat and light, and explained that a solar system is a collection of bodies that revolve around a central star, including planets, moons, comets and asteroids.
