Evolution of the radii using the parameters given in Valle et al. (2017). The F and M models are shown in red and blue respectively. The F and M models numbered with I, II, and III are represented by solid, dotted, and dashed lines respectively. The F-I/II model is shown with a dashed dotted line. From top to bottom, the panels show the evolution of the primary’s radius relative to its Roche radius, and the primary and secondary radii. The corresponding observed radii including the error ranges are indicated by the horizontal grey long- and short-dashed lines
