There are 2 lessons in this physics tutorial covering Evolution of Stars. The tutorial starts with an introduction to Evolution of Stars and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Evolution of Stars. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

  • How a star is created?
  • What are the factors affecting the stability of a star?
  • How long did it take to the Sun to take the actual shape? When did it start existing?
  • What are the stages a star comparable to our Sun undergo during its existence?
  • What about much bigger stars?
  • What is gravitational collapse? When does it occur?
  • What are neutron stars? Why do we call them so?
  • What is a supernova? How does it looks in the sky?
  • What is a pulsar?
  • How planetary nebulae are formed?
  • What are black holes? Can we see them from Earth?

Introduction

What type of celestial bodies are stars? Do they produce energy by themselves or do they obtain it from other sources?

Do you think the Sun will continue to exist forever? Why do you think so?

What kind of stars do you see when observing the sky at night? Is there any star that emits its light with interruption?

Is it appropriate to consider a star as similar to a living organism? Why?

This tutorial aims to explain how different stages of a stars existence develops. All stages in which a star passes from its creation to the end of its life are explained for two seperate categories of stars: those with dimensions similar to Sun and those that are much bigger than the sun. It is important to consider the two types seperately as the evolution of the two-aforementioned types of stars differ at a certain point of their existence.
