    1. Stars are made up of hot gases. The two major gases are hydrogen and helium.

  2. In your video, you talked about how low mass stars live a shorter life than high mass stars. Why is this? What causes low mass stars to live longer?

    1. high mass stars require more hydrogen to fuse at a time, so it lets out more energy which speeds up its life cycle. A low mass star doesn't have to use as much hydrogen at a time so its life span is a lot longer.

  3. What happens if the protostar does not reach the main sequence star phase?

  6. What causes a star to produce stellar winds, such as those that clear the gas surrounding a protostar?

    1. the stellar winds are formed when materials like protons, electrons and atoms that are ejected from stars.

  7. how does a star turn into a black hole?

    1. thats a good question Will. However, only stars with really large masses (even ones bigger than our own sun) can form black holes. When this particular star runs out of nuclear fuel, the gravity begins to take over by compressing the material in its core. The more massive the core of the star, the greater the force of gravity that compresses the material, collapsing it under its own weight. This forms a black hole.
