Allers et al., 2020 : 2MASS J10475385+2124234 is a T6.5 BD of 0.5 to 10 billion years with an estimated temperature of 880+/-76 K, a rotation period of 1.77 ± 0.04 hours and a magnetic field strength of 5.6 kG. The difference between radio period and infrared period implies a wind of +650 ± 310 m/s proceeding eastward.
