Chapter 28 Stars and Galaxies Notes
• What is light– Electromagnetic radiation: energy that travels in
waves– Electromagnetic spectrum: continuum of various
types of electromagnetic radiation
Doppler Effect
• https://search.yahoo.com/yhs/search?p=doppler+effect+animation&ei=UTF-8&hspart=mozilla&hsimp=yhs-002
• https://www.youtube.com/watch?t=21&v=eo_owZ2UK7E
• Doppler effect: applies to sound as well as light– Can be used to determine whether a star is
moving toward Earth or away from it– Shorter wavelengths of light have a blueshift –
meaning they shift toward the blue end of the spectrum (star is moving towards Earth)
– Redshift – (star is moving away from Earth) star’s spectral lines shift toward the red end of the spectrum.
Stars and their Characteristics
• Constellations: groups of stars• Earth’s motion (rotation and revolution)
affects the movement of the constellations across the sky
• Constellations position in the sky changes with the seasons– Circumpolar stars – when viewed from some
northern latitudes, these constellations never set below the horizon and can be seen all year long
Distance and Space
• Apparent magnitude – measure of how bright a star appears to be to an observer on Earth– Lower the number = brighter star
• Astronomical unit (AU) – the average distance between Earth and the sun is 150 million kilometers
• Light year – unit that measures the distance that a ray of light travels in one year
Distance and Space
• Parallax – a change in a object’s direction due to a change in the observer’s position– ***Practice Parallax***
• Parsec – the angle between two observed positions and the distance between the observation points– 1 parsec = 3.258 light years
Mass, Size, and Temperature of Stars
• Stars: sphere of super hot gases – mostly hydrogen and helium– No two stars have the same elements in the same
proportions• Stars vary more in size than they do in mass– Mass: can’t determine directly, can only calculate
what it might be• Expressed as multiples of the mass of the sun (solar
mass)
Warm-up (9-16-15)
• Explain how stars are classified. Try to be as specific as possible.

sun and the Earth and what processes can be affected by the sun here on Earth.
Mass, Size, and Temperature of Stars
• Temperature and color of stars– Colors depend on surface temperature
• What happens when metal is heated??
– Hottest objects glow with a bluish light– Cooler objects have a reddish glow
• Luminosity: actual brightness of a star• Depends only on size and temperature
– Absolute magnitude: measure of how bright the star would be if all stars were at the same distance from Earth• How astronomers express the true brightness of a star
Life Cycle of Stars
• Hertzsprung-Russell Diagram• Shows the relationship between the
temperature and the luminosity of stars– Main Sequence Stars: (90% of stars) High
luminosity, high surface temperature to low luminosity, low surface temperature
– Giant Stars: have diameters from 10-100 times greater than that of the sun
– Supergiants: stars with diameters more than 100 times the sun
Life Cycle of Stars
– White Dwarfs: stars that are near the end of their lives• Used to be red giants but lost outer atmosphere and now
are the glowing core
• Birth of a Star– Nebula: cloud of gas and dust, the beginning of a star– Outside force causes contraction, increases
temperature, may cause glowing portions (protostar), increasing temperature and brightness as contraction continues. Protostar may become so hot that fusion starts = a star is born!!!!!

Death of a Massive Star
• Explosion of a red super giant causes the creation of a supernova (millions of times brighter than the original star’s brightness
• Remnants of massive stars– Neutron star – named for the effect gravity had on its
atomic structure – dense mass of neutrons• Pulsar – rapidly spinning neutron star – give off pulses of
energy
– Black hole – remnant of a star at least 15 times as massive as the sun, gravitational force is so strong that light cannot escape
Galaxies and the Universe
• Galaxies – systems containing millions or even billions of stars– We are in the Milky Way galaxy and the Local Group
(about 30 galaxies)• No two galaxies are exactly alike• Active galaxies – emit more energy than could be
given off by their stars– May be powered by a supermassive black hole at its
center– Quasars – extremely distant objects, luminous,
Warm-up (9-17-15)
• Explain what the lifecycle of a star is. Include what happens when a sun-size star dies.

Expansion of the Universe Lab p. 636
• Prediction: (How many mm will the universe expand by every 8 years?)
• DATA: (cut and paste data table into your notebook)
Expansion of the Universe Lab p.636
• Procedure– Use a fine-tip marker marker to mark 13 dots around the surface of the deflated
balloon. Mark dots only on the round, inflatable part of the balloon, not the stem. Be sure to distribute the dots all over the balloon. Label the dots A through M randomly.
– Inflate the balloon until its diameter is about 8cm. Pinch and fold the stem over and use a binder clip or paper clip to keep air from leaking out.
– Use a piece of string to measure the distance in mm from point A to each of the other 12 points on the balloon’s surface. Copy the data table below to record the results as “Distance at time = 8 years”
– Unclip the balloon and inflate the balloon until it has a diameter of about 16cm. Re-clip the stem to prevent air from leaking out.
– Use a piece of string to measure the new distance in mm from point A to each of the other 12 points. Write the results in the data table in the row “Dsitance at time = 16 years.”
– Subtract the distances at time = 8 years from the distances at time = 16 years. Record the result in the row “Distance increase(mm)”
Expansion of the Universe Lab p.636
• Procedure– Assume that the distance measurements were actually taken eight years apart.
Compute the average speed that each point is moving away from point A. Record your answer in the row “Rate of distance increase” HINT: speed = distance/time
– Make a scatter plot of the data from your calculations made during step 5 and 7. Label the x-axis with “Distance at time = 16 years” label the y-axis with “Rate of distance increase” Draw a best-fit line for the points on the scatter plot
– Using the rates from Step 7, predict how far each point on the balloon would be from point A at a time of 24 years. Assume the balloon will expand at the same rate as it did between times of 8 and 16 years. Record your predictions in the “predicted distance at time = 24 years”
– Unclip the balloon’s stem and inflate the balloon so that its diameter is approximately 24 cm. Re-clip the stem
– Use the string to measure the distance between point A and the other points of the balloon. Record the distance in the row “Measured distance at time = 24 years”
Analysis and Conclusions1. Calculate the slope of the best-fit line in your scatter plot from Step 8. What
are the units for the slope of the best-fit line? What does the slope of this best-fit line represent?
2. Give a few examples of possible sources of error for the predictions you made of any distances from point A at a time of 24 years
3. This activity was done from the point of view of a two-dimensional being living at point A in Balloonia. Would the expansion of Balloonia appear faster or slower if this being lived at one of the other points?
4. From the point of view of a being living on Balloonia, where is the center of the expansion of the universe? Remember that this being can only see along the surface of the balloon. Where is the center of the Balloonia universe according to an outside observer?
5. Astronomers today theorize that our universe is expanding, similar to the way all points on Balloonia Move away from each other as the balloon inflates. If this theory is accurate, where is the center of our universe?
