Episode 117: A Field Day

About this episode

This episode discusses various fields in astrophysics, including Lagrange points and the atmospheres of hot Jupiter exoplanets.

In this episode, we move away from point particles to talk about fields. Shashank, Cole and Cormac start with a discussion of different kinds of fields in astrophysics. Then, Cole describes Lagrange points and why they can be useful for satellites and asteroids seeking a safe place to camp out (or lay siege). Cormac dives into the atmospheres of hot Jupiter exoplanets, where we get a glimpse of temperature and wind velocity fields on other planets. By the end, you’ll certainly have a lot more field experience!
