39 hr diagram lab
The Hertzsprung-Russell Diagram. Figure 10.12 plots luminosity versus temperature for a few well-known stars. A figure of this sort is called a Hertzsprung-Russell diagram, or H-R diagram, after Danish astronomer Ejnar Hertzsprung and U.S. astronomer Henry Norris Russell, who independently pioneered the use of such plots in the second decade of the twentieth century. Lab Task 1: Plotting 6 Stars on an HR Diagram The overall goal of the lab is simple: Complete Tables 1 & 2, plot the stars on the provided HR diagram, and then calculate the radii of the stars. You will use Stellarium to "observe" three of the six stars. The stars you are observing include: Three F-type stars, a B-type supergiant, a M- The short video explains how to read the different axes of the H-R diagram. There are 3 questions related to the H-R diagram which students will answer on their lab sheet. RESEARCH IT! The research station will allow students to go online and interact by categorizing ...
