Difference between stellar abundances of HD 110058 and HD 100546 in increasing order of condensation temperature. The abundances are on a logarithmic scale. The highlighted regions in red (top) and blue (bottom) represent the radial disc’s mid-plane dust temperatures for HD 100546 and HD 110058, respectively. For HD 100546, we used the mid-planet dust radial temperature profile from Keyte et al. (2024). For HD 110058, we used the Stefan Boltzmann law and stellar luminosity to estimate the radial temperature profile for the debris disc and giant planet. The vertical lines indicate the temperatures at the position of the planets (confirmed or predicted) in the radial disc temperature profiles around both stars.
