Evolution of the water ice sublimation front and the central temperature for the nucleus of P/2010 A2. The x-axis represents the time [yr] in log scale since the placement of the object in its current orbit, the y-axes represent: a) the sub-surface depth where crystalline ice survives; b) the central temperature. Case I (“asteroid”) is plotted in black, while Case II (“comet”) is plotted in gray.
