  "abstract": "SN 2024abup is a nearby broad-lined Type Ic supernova (SN Ic-bl) in NGC 0681 at a distance of 23.3 ± 1.6 Mpc. As energetic explosions of massive stars, SNe Ic-bl are considered a plausible site for rapid-neutron capture nucleosynthesis ( r -process) and chemical enrichment from short-lived progenitors. They may also contribute to dust production in the early Universe. We present JWST near- to mid-infrared (NIR+MIR) observations (1–14 μ m) of SN Ic-bl 2024abup at +41 days after the V -band maximum (+54 days after explosion), the first-ever JWST+MIR observation of an SN Ic-bl along with radio and optical data. Using the spectral synthesis code SUMO , we identify the observed broad IR line features in SN 2024abup and find significant contributions from C, O, Mg, and carbon monoxide (CO)—the earliest detection of molecules in a core-collapse SN so far. The spectrum shows continuum emission at wavelengths greater than 1.5 μ m, which could be explained by dust—preexisting, newly formed, or a combination—heated by the SN. We do not find unambiguous evidence for infrared signatures of r -process elements, though our search is hampered by the presence of many broad and blended features from the non- r -process elements such as [Te iii ] + Mg ii at 2.1 μ m. These new observations indicate that SNe Ic-bl could be a contributor to early-universe dust production and suggest that if r -process elements are produced, revealing their presence from spectra requires very high-quality data and models to disentangle blends.",
