10/24/16 STELLAR FORMATION Objective: I will illustrate the steps in the formation of a star. PAGE 27 What is a star? • A large object made of gases that gives off light and heat What is a star? • Made of mostly Hydrogen (H) gas Formation of a Star • nebula- cloud of gas and dust from which stars form Formation of a Star • gravity causes the nebula to contract • as more matter is pulled together, gravity increases Formation of a Star • the nebula begins to spin and flatten into a disk Formation of a Star • protostar (pre-star)- central concentration of matter in the middle of the spinning nebula Formation of a Star • as gravity increases, temperature and pressure build • eventually, nuclear fusion occurs • a new star is born! Left Side Output Activity Page 26 • Use the diagram on page 436 in the Purple Textbook and your notes to complete the following: • Diagram the steps in the formation of a star • Label each step with a brief description
