Comparison of temperatures (upper panel) and their corresponding density profiles (lower panel). Upper panel: black line is the temperature resulting from the maximum speed of sound of Salz et al. (2016) and our averaged mean molecular weight; the cyan line is the maximum of the temperature profile of Salz et al. (2016), and magenta is their temperatureprofile. Lower panel: density profiles calculated by Salz et al. (2016) (magenta) and those calculated using our model (black and cyan).
