Even: Blackbody radiation
Makeup quiz on reading.
More notes;
Blackbody radiation
Wien's Law and the Stefan-Boltzmann Law
Blackbody simulator
How to use Graphical Analysis 3
Assignment: Analyze the following:
69 Cygnus
41 Cygnus
Wolf 1346
Nova Aquilae 1999
Arcturus
Deneb
Sigma Serpentis
Tell:
The kind of spectra it is
Whether or not it is a blackbody
What elements are in it
If it is a blackbody:
it's peak radiation color
Temperature from Wien's law.

Finish nova lab; move on to color topics
Finish Nova Search lab and turn in.
Review brightness information
Introduction to color
Color is a wavelength or frequency of light
The electromagnetic spectrum
Energy is directly related to wavelength
Types of spectra (demonstration)
continuous - generated by hot opaque objrects
emission - generated by hot transparent gases
absorption - continuous spectra source surrounded by cool gas

New system for posting
I'm going to start just posting the even-day schedule since the odd-day schedule duplicates ti. 7th period, look at the entry the day AFTER you see me to find your scheduled activity or notes.

Odd: light curves 1
Simulating the orbital period of a binary star system
We will simulate the orbit of a binary star and then analyze the data in a classroom activity.
We introduce the concept of converting brightnesses to magnitudes with some rather thick notes that conclude with this equation:
m (unknown) = 2.5 log (brightness known/brightness unknown) + m(known)
Then we started an activity which used this equation to compute some unknown magntiudes in a picture.
