[2] WISE 0825+2805 was discovered in 2015 by Schneider et al. with the Wide-field Infrared Survey Explorer and the Hubble Space Telescope, using WFC3 near-infrared grism spectroscopy.

[1] WISE 0825+2805 was observed with JWST NIRCam and MIRI.

The good fit requires an effective temperature of 350 Kelvin and a surface gravity of log g = 4.0.

Alternatively a lower surface gravity could improve the fit.

The model parameters correspond to a mass of 5 MJ and an age of 800 Myrs.
