[3] A later work from 2023 found a mass of 17 ±5 MJ.

[4] It was observed with JWST, using NIRSpec and MIRI spectroscopy.

This object is not discussed in detail in this work, but the researchers report the detection of molecular absorption features in their sample, including water vapor, methane, ammonia, carbon monoxide and carbon dioxide.

[5] One paper mentions that WISE J1206+8401 does have deeper carbon dioxide and carbon monoxide features, when compared to other Y-dwarfs.

This makes this Y-dwarf similar to CWISEP J1047+5457.
