IRE 14 Primary is a T-Tauri type variable. Kraus et al. (2014) estimate the
mass of the companion at 16 +/- 1 Mjup . KsA2014
Lachapelle et al. (2015) derive the following properties:
Spectral type | K7 +/- 0.5 | M9 +/- 0.5
Teff (K) | 4200 +/- 150 | 2300 +/- 100
log(L/Lsun) | -0.42 +/- 0.08 | -3.01 +/- 0.09
Mass (Msun) (5 Myr) | 0.9 +/- 0.1 | 0.015 +/- 0.001
Mass (Msun) (10 Myr) | 0.9 +/- 0.1 | 0.016 +/- 0.001
Distance (pc) | 145 +/- 14 | ...
Projected separation (AU) | | 320 +/- 30 Lch2015
