Kippenhahn plots derived from the MESA model with conservative mass transfer for V1001 Cen. At the top we see graph donor star and below gainer star for a conservative model of initial mass of 4.4 and 1.4 M/M_⊙ and initial orbital period of 2.1 days. In the graphical representation, the x axis displays the age since hydrogen ignition in units of million years (Myr), and the different stellar layers are identified by their mass proportions (M/M_⊙). Each mixing process is illustrated with specific colors and patterns: convective mixing is represented in green with a hatching pattern, semi convective mixing in red, convective overshooting mixing with a crosshatched pattern in purple, and thermohaline mixing in yellow with a hatching pattern. The solid black line indicates the surface of each star, and the brown zones correspond to rotational mixing.
