Bonnefoy et al. (2014): models with dust reproduce the spectral distribution better.

Hinkley et al. (2013) give the significantly different estimate for the age of the system of 200±100 Myr, from which they infer a much higher mass: 50-13+16 Mjup, and an effective temperature of 2040±60K.

Carson et al. (2013) derive a semimajor axis of 61-20+50 AU from the projected separation of 55±2 AU using the method of (Dupuy et al., ApJ, 721, 1725, 2010).

The age of the system has been called into question, other estimations giving a much older age of ~200 Myr (see for example Hinkley et al. 2013).
