List the following stages of stellar evolution in order for a certain star that has a mass of 80% of the Sun:
- A white dwarf
- A nebula
- A red giant
- A main sequence star
- A protostar
For approximately how long does a star like the Sun remain a main sequence star?
Which of the following is the correct description of a black dwarf star?
The heat generated through nuclear fusion in a star’s core exerts an outward force on the material around it. This would cause the star to expand, but it is balanced by another force acting upon the material in the star, which keeps it stable. What is the other force acting on the matter in the star?
Which of the following is the correct description of a nebula?
The diagram shows nine possible stages in the evolution of a star. For a star that will eventually become a neutron star, give the correct stages in the correct order, starting from a nebula.
