Using the doppler shift, we should be able to tell if a star is moving

Which of the following travels the fastest?

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
Brightness of the star		pattern of the light tells us the makeup of the outermost layer of the earth
spectral analysis of the light		whether the star is moving towards or away from the earth
luminosity of the star		how much light is observed from earth
distance of the star		light output of the star based on light observed from earth and calculated distance to the star
size of the 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.
the mass of a 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)
doppler shift of the spectral analysis		from measuring the speed of the orbits of the stars planets

Match the layer of the sun to an aspect of that layer

Draggable item		Corresponding Item
photosphere		Energy is released by fusion
Convection zone		Energy is moved by photons being released, reabsorbed, and released again
Chromosphere		Energy is carried by moving atoms rather than photons
Core		transition layer where gases move from being transparent to opaque
corona		thin layer with strong red-emission lines that can be seen during an eclipse
Radiative zone		third hottest layer of the sun that has lowest amount of energy because of its low density

astronomical unit

finding the angle between the line of site from one side of an object to another

semi-major axis

the distance from the center of an ellipse to furthest point

angular size

the average distance from the earth to the sun 

ellipse

the time interval of a repeating cycle

Energy can neither be created or destroyed

an object in motion stays in motion until acted on by an unbalanced force

Entropy is always increasing

force= mass x acceleration

you can never achieve absolute 0

For every action there is an equal and opposite reaction

how the position of an object changes with respect to its background when seen from different positions

parallax

the idea that the earth is the center of the solar system

epicycle

how planets seem to move backwards in their orbits

retrograde motion

a small circular orbit whose center moves around a larger circular orbit

Gradual slowing down of rotation due to tidal forces

Eclipse

Rotates at the same rate as orbit

the time it takes the earth to pass these sections are the same if the angles are the same
