Spectral energy distribution of AT 2011kp as obtained from JWST observations performed in 2023 and 2024 (13 years after the LRN onset), from 1.15 to 7.7 μm (black points). Downwards arrows mark upper limits. The SED is best-fitted with three DUSTY models with different chemical compositions: 100% silicates (top panel), 50% silicates + 50% AMC (middle panel), and 100% AMC (bottom panel). Contributions from dust emission, attenuated, and scattered light are also shown. The excess at 1.8 μm is marked with a rhombus.
