Color-magnitude diagram of late-T and Y dwarfs in Spitzer colors. Effective temperatures have been estimated using color-temperature relations from Kirkpatrick et al. (2019). Our target, W0146, is shown as a star. Its best fit single is W0535, slightly fainter and redder. The components of its best fit binary template are W0751 as a primary, and W1405 as a secondary. The addition of these two spectra would produce a blended-light template that is redder than expected for its temperature. Three other confirmed binary systems straddling the T/Y transition are shown as squares: WISE J1711+3500 (Liu et al. 2012), WISE J1217+1626 (Liu et al. 2012), and W0336AB (Calissendorff et al. 2023). -- astro-ph.SR

We present the first brown dwarf spectral binary characterized with JWST: WISE J014656.66+423410.0, the coldest blended-light brown dwarf binary straddling the T/Y transition.
