Context. Observations of edge-on disks are an important tool for constraininggeneral protoplanetary disk properties that cannot be determined in any otherway. However, most radiative transfer models cannot simultaneously reproducethe spectral energy distributions (SEDs) and resolved scattered light andsubmillimeter observations of these systems, due to the differences in geometryand dust properties at different wavelengths. Aims. We simultaneously constrainthe geometry of the edge-on protoplanetary disk HH 48 NE and thecharacteristics of the host star. HH 48 NE is part of the JWST early releasescience program Ice Age. This work serves as a stepping stone towards a betterunderstanding of the disk physical structure and icy chemistry in thisparticular source. This kind of modeling lays the groundwork for studying otheredge-on sources to be observed with the JWST. Methods. We fit a parameterizeddust model to HH 48 NE by coupling the radiative transfer code RADMC-3D and anMCMC framework. The dust structure was fitted independently to a compiled SED,a scattered light image at 0.8 ${\mu}$m and an ALMA dust continuum observationat 890 ${\mu}$m. Results. We find that 90% of the dust mass in HH 48 NE issettled to the disk midplane, less than in average disks, and that theatmospheric layers of the disk contain exclusively large grains (0.3-10${\mu}$m). The exclusion of small grains in the upper atmosphere likely hasimportant consequences for the chemistry due to the deep penetration ofhigh-energy photons. The addition of a relatively large cavity (ca. 50 au inradius) is necessary to explain the strong mid-infrared emission, and to fitthe scattered light and continuum observations simultaneously.
