There is much more that we can and will say about stars, but we are definitely getting there. Now that you have some feel for where stars form (nebulae), how stars form, and the astronomical uses of binary stars, we will move into a discussion of what happens next -- how stars evolve after they run out of hydrogen and how they eventually die.
Activity 1 - Lesson 5 Quiz
First, please take the Web-based Lesson 5 quiz.
- Go to Canvas.
- Go to the "Lesson 5 Quiz" and complete the quiz.
Activity 2 - Discussion
For this activity, I want you to reflect on what we've covered in this lesson and to speculate about the evolution of binary stars. Since this is a discussion activity, you will need to enter the discussion forum more than once in order to read and respond to others' postings.
Submitting your work
- Enter the "Binary Star Evolution" discussion forum in Canvas.
- Post your ideas about the topic I have posted to that forum.
- Read postings by other ASTRO 801 students.
- Respond to at least one other posting by asking for clarification, asking a follow-up question, expanding on what has already been said, etc.
You will be graded on the quality of your participation. See the grading rubric (identical to the one for Earth 530) for specifics on how this assignment will be graded
Activity 3 – Lab 2 part 1
During this week, you should begin work on the lab exercise that will be completed and submitted by the end of Unit 2.
- "Lab 2 part 1" is located on the next page.
- Follow the instructions to create your first two sample HR diagrams.
Reminder - Complete all of the lesson tasks!
You have finished the reading for Lesson 5. Double-check the list of requirements on the Lesson 5 Overview page to make sure you have completed all of the activities listed there before beginning the next lesson.
