Week 9 Overview
Overview
This week, we will have a special event visiting the "Celestial Observation Show" at Clark Planetarium in Salt Lake City on Monday and Wednesday at 7pm! Please find detailed information and instructions in the Canvas announcements.
In class, this week we will be focusing on how a low-mass star, such as our Sun, evolves over time.
By the end of this week, you should be able to:
- use the mass of a main-sequence star to estimate its lifetime.
- explain why the Sun will grow larger and more luminous when it runs out of fuel.
- sketch post-main-sequence evolutionary tracks on an H-R diagram.
- describe how planetary nebulae and white dwarfs form.
- explain how white dwarfs in a binary system may evolve differently than solitary white dwarfs.
