Redder than Red: Discovery of an Exceptionally Red L/T Transition Dwarf (Schneider A. et al., 2023, ApJ, 943L..16)
UKIRT has discovered a free-floating planetary mass brown dwarf, J050626.96+073842.4 (pictured above). J050626.96+073842.4 has the reddest known colors of any brown dwarf around L/T transition — young and very dusty atmosphere. Below is photometric data from the UHS survey and the USNO-UKIRT parallax.
