11.1: Introduction
Astronomy Laboratory 11 – The H-R Diagram
Module Introduction
The Hertzsprung-Russell Diagram, H-R Diagram, is a useful tool which plots stellar luminosity versus temperature. Building on the Star Colors and Spectroscopy lab, you will detail how the H-R Diagram works, and plot some of the stars observed in Lab 10, Star Colors and Spectroscopy. (1)
Objectives
At the end of this module, students will be able to:
- Plot a H-R diagram using provided data
- Analyze the data and make interpretations using the H-R diagram (1)
