Projection in the orbital plane depicting the evolution of Model C in Table 2, from the initial Roche-lobe contact until the formation of a single object composed by the core of the red giant surrounded by a Keplerian disk made of the debris of the former He white dwarf. The scale along the sequence represents the logarithm of temperature in Kelvin degrees. Each snapshot is a 10¹¹ by 10¹¹ cm box centered on the center of mass of the system.
