PDFs given by PASTA for the considered planetary parameters in the K2-285 system: semi-major axis (first row), mass (second row), and (third row). The black curves in each panel of the third row (evident in the second panel, and just barely visible in the others as they are squeezed towards zero) indicate the predicted present-day atmospheric mass fraction. It follows that K2-285 b, d, and e have almost entirely lost their atmospheres at some point in time along the system’s evolution.
