Left: raw yield as a function of the BDT selection and extracted contributions from prompt and non-prompt D$^*$ mesons with $4 < p_{\rm T} < 6$ GeV/$c$ and $|y| < 0.8$ in the 30$-$50% centrality class. Right: measured fraction of prompt D$^*$ mesons as a function of $p_{\rm T}$ in the 0$-$10% and 30$-$50% centrality classes. Only the statistical uncertainties are reported.
