Astronomy 200/210 Lab Project #2 - Stellar Classification |
Introduction The purpose of this project is to give you experience in interpreting stellar spectra and to better understand the stellar spectral classification system. In preparation for this project you are encouraged to review the following lectures: How to Use the Applet Spectral Analysis In class we will look at the applet Spectral Analysis and how you are expected to use it. You may find the following videos helpful to refresh your memory on how to use the applet and interpret spectra.

Video 3: Identifying spectral lines - part 2 |
What to Do... Load the applet (this link will open in a separate window) and analyze each of the 15 spectra. On the answer form (see below) identify the spectral types. Included in the spectra are all of the 7 major classes (O,B,A,F,G,K,M) as well as:
