Movies Made Using Common Envelope Simulation Output

The relevant references for these movies are:
Paper I: Chamandy+2018 "Accretion in Common Envelope Evolution"
Paper II: Chamandy+2019a "Energy Budget and Core-Envelope Motion in Common Envelope Evolution"
Paper III: Chamandy+2019b "How Drag Force Evolves in Global Common Envelope Simulations"
Units on colorbars are CGS (except for in some cases where dimensionless units are used).
