Complete elemental abundances beyond Fe of 2M22480199 (left panels) and zoomed over a smaller mass range (right panels) compared with i-process simulations that peak in the Zr region (la, upper panels) and at Ba (lb, middle panels), and with s-process simulations from fast-rotating massive stars (1c, lower panels). The elements with the most reliable observational results (measurements or upper limits) are highlighted with large orange circles. Stellar simulations are diluted with pristine material to reproduce the abundance of the reference element Zr (upper and lower panels) or Ba (middle panels). The results from the dilution with two different pristine components are shown: solar scaled, and modified by 0.2 dex from solar (see the text for details).
