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 stars on an H-R diagram according to brightness and temperature.

Hr diagram lab. The Hertzpsrung-Russell (H-R) diagram is a way of categorizing properties of all stars in the sky, including the Sun. The surface temperature, color, luminosity, and radius of stars can all be deduced from their location on the H-R diagram. When a star begins to condense from an interstellar dust cloud, it enters the HR diagram in the middle right. We have learned this by studying H-R diagrams, particularly for large groups of stars (like the Pleiades and M67 clusters featured in this lab exercise).28 pages Lab - HR Diagram p - 0708.pdf ...

HR Diagram Lab. Uncheck the plotted stars option the nearest stars and check the brightest stars (pictured below). Why are these stars the brightest in the sky? Three students debate this issue: Student A: "I think it's because these stars must be very close to us. That would make them appear brighter to us in the sky."

The H-R Diagram is a tool that astronomers use to classify stars based on their luminosity, magnitude, temperature, spectral class and evolutionary stage. The H-R Diagram was independently discovered in the early 1900's by the Danish astronomer Ejnar Hertzsprung and the American astronomer Henry Norris Russell.
