Now that exhibition is over we are going to start putting aspects of light together. so first - some review: below is a list of things we can glean from light from a star. From what you already know, try to match the aspect of a star we can learn

Draggable item		Corresponding Item
distance of the star		pattern of the light tells us the makeup of the outermost layer of the earth
doppler shift of the spectral analysis		whether the star is moving towards or away from the earth
Brightness of the star		how much light is observed from earth
luminosity of the star		light output of the star based on light observed from earth and calculated distance to the star
the mass of a star		parallax, speed of doppler shift,
Age of a star		uh... we can't really tell that about an individual star. we have theories about stars in general.
size of the star		angular diameter, and then calculate the linear measurement with the distance found with parallel. (there are other methods of making more precise measurement as well)
spectral analysis of the light		from measuring the speed of the orbits of the stars planets
