AS102 Study Guide - Final Guide: Main Sequence
Document Summary
So, in determining a star"s spectral type (indirectly, temperature) and luminosity we are really learning more about its mass than anything else. Clearly, they are all tied together but mass is the most important factor. The neat animation listed below allows you to build a new star by adjusting the temperature of the new star in the bottom left box along with its luminosity using the slider right below the temperature one. Here you will see that in order for the new star to be on the main sequence (red) line on the h-r diagram the temperature and the luminosity have to be perfectly adjusted. Below these sliders the radius of the star is calculated as you adjust the sliders. Try setting the surface temperature at 14000 k; you will find that the luminosity has to be set at about 160 l (meaning.
