Logarithmic plot of the radial temperature profile used to model the ¹²CO disk surrounding L₂ Pup, as a function of distance from the central star. The red line represents the continuous expression. The black dotted line is the closest approximation of the red curve by a set of subsequent power laws. The blue dotted line continues the temperature trend of the gas, devoid of dust. The temperature parameter values, and the slopes of the power laws are listed in Table 5.
