# 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).

## Movies corresponding to figures in Paper III (for Model A and Models B and C of Paper III). Companion (particle 2) at center of frame, red giant core (particle 1) located on -y axis.

Figure 6 first row—-face-on force density on particle 2 in rest frame of particle 1 in dyn/cm3 (contours equal to values on colorbar, blue arrow shows velocity of particle 2 in rest frame of particle 1, black arrow shows net force on particle 2 in rest frame of particle 1):

Figure 6 second row—-face-on density normalized to value at radius r=a(t) of initial envelope profile. Vectors show velocity field projected in orbital plane in co-orbiting and co-rotating rest frame of particle 2:

Figure 6 fourth row—-face-on tangential velocity (with respect to particle 1) normalized to value calculated assuming a circular orbit at radius r=a(t) and density profile of initial envelope (assumed non-rotating). Vectors show velocity field projected in orbital plane in co-orbiting and co-rotating rest frame of particle 2:

Figure 6 fifth row—-face-on sound speed (with respect to particle 1) normalized to value at radius r=a(t) of initial envelope profile. Vectors show velocity field projected in orbital plane in co-orbiting and co-rotating rest frame of particle 2:
Face-on normalized sound speed (Model A: No subgrid accretion, M2 = 1 Msun)

## Movies corresponding to figures in Paper II (for Model A and Models B and C of Paper III)

Movies are in the lab (~system CM) reference frame with the CM of the particles located at the center of the frame.

Figure 3 top row—-face-on normalized gas binding energy (red means unbound, blue means bound, yellow is density contours, vectors show velocity):

Figure 3 second from top row—-face-on normalized gas kinetic energy (magenta means thermal energy dominates, green means bulk KE dominates, yellow is density contours, vectors show velocity):
Face-on normalized kinetic energy (Model A: No subgrid accretion, M2 = 1 Msun)

## Movies corresponding to figures in Paper I (for Model A and Models B and C of Paper III and Model B of Paper I)

Movies are in the reference frame corotating about the secondary with the instantaneous orbital angular speed of the particles, and with the secondary at the center.
