Zakamska et al. (2025): A circumplanetary disk as large as 0.7 AUs surrounds the substellar occulter.
Shah et al. (2025). A second transit model points to an occulting substellar companion, either gas giant or brown dwarf, surrounded by a 0.17 AUs-wide circumplanetary disk or rings. Near-infrared spectra taken during dimming show enhanced infrared excess and spectral features consistent with an M8-type companion.
