Corrigendum: How drifting and evaporating pebbles shape giant planets (Astronomy and Astrophysics (2021) 654 (A72) DOI: 10.1051/0004-6361/202141096)

The published Papers I and II made use of a chemical partitioning model that did not conserve the nitrogen abundance. The correct N2 abundance should have been 0.45 x N/H instead of 0.9 x N/H (see Table 1). This change in the N2 abundance results in a wrong ratio of nitrogen-bearing species to other molecular species, even though the total heavy element content was still conserved. Rerunning all simulations, we find that the general outcome of our simulations remains unchanged, except for the nitrogen content shown in Paper II. We have therefore updated Figs. 2, 3, and 5 from Paper II to include the updated chemical model with the correct partitioning of nitrogen. Correcting the fraction of N2 by decreasing N2 slightly increases the amount of other heavy molecular species, as can be seen in Figs. 1 and 2. The resulting volatile-to-refractory ratio is therefore subsequently slightly smaller, since N2 is volatile. The model of Jupiter and Saturn with additional solid enrichment has been updated to include less solids (see Table 2) to still match the sulfur abundance of Jupiter and Saturn. The updated Fig. 3 still demonstrates that Jupiter's nitrogen abundance could have been influenced by the drift and evaporation of N2-bearing pebbles. While there is a slight difference in the nitrogen abundance in the planetary atmospheres from the updated model, the general conclusions of our simulations in Papers I and II remain untouched.
