The Diversity of Cold Worlds: a blended-light binary straddling the T/Y transition in brown dwarfs

Daniella C. Bardalez Gagliuffi, Jacqueline K. Faherty, Genaro Suarez +22

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. We o…
