von Essen et al. (2020) : From the secondary eclipse estimate a day side temperature of 3014 K and a night side temperature of 1605 K.
Smith et al. 2011 : The mass upper limit is at the 3 sigma level
Smith et al. 2011 : : Tbrigh = 3620 -250/+200 K, Tequ for isotropic re-radiation =2750 ± 37K , Tequ for day-side re-radiation = 3271 -/+ 44K. T for zero-redistribution =3515 -/+47K
Wright et al. 2023 measured a vibrational temperature of 2815 K.
