Spectral decomposition of the 6.2 (top), 8.1 (middle), and 11.3 (bottom) μm AIBs observed in the JWST spectrum of T Cha. Band profiles are fitted with Drude profile components (blue solid lines). The sum of the underlying stellar and dust continuum is shown in red solid line. The black dashed line shows the total fit to the AIB profiles. See more details in Sect. 4 and Appendix A.
