ASTR 1102 Lecture 11 Notes

  • SLIDE 3

    • higher density of gas = stronger gravity

    • stronger gravity can make gas cloud collapse


  • SLIDE 4

    • sun’s core = 16mil Kelvin


  • SLIDE 11

    • stars have magnetic forces


  • SLIDE 13

    • escape velocity


  • SLIDE 17

    • the corona is hotter than the atmosphere because of an additional source of heating that warms up the solar surface


  • SLIDE 21

    • magnetic forces will slow down convection causing sun spots
