Presentation Transcript

  1. H-R diagram and star magnitude

  2. Star magnitude • Magnitude or luminosity- The brightness of a star

  3. Apparent magnitude demonstration

  4. Absolute vs. Apparent magnitude • Apparent magnitude Apparent magnitude- how bright a star appears to us fromEarth.

  5. Absolute Magnitude • The absolute truth!!! • The absolute magnitude is the true brightness of the star no matter where it is in space!

  6. So, do you think: How bright a star is has anything to do with how hot the star is?

  7. H-R diagram • Scientist tried to find this out so they graphed it. • The result was an Hertzsprung-Russell Diagram • Pg 289- q on 307
