Abstract
We present results of modelling the bulk of the spectral energy distribution (0.45 - 5 μm ) for GJ406 (M6V). Synthetic spectra were calculated using the NextGen model atmospheres of Hauschildt et al. (1999) and incorporate line lists for H2O, TiO, CrH, FeH, CO, MgH molecules as well as the VALD line list of atomic lines. The computed water partition function is in a good agreement with Vider & Tennyson (2000). A comparison of synthetic and observed spectra give Teff= 2800 ± 100 K. For Mbol = 12.14m we thus derive an age of t = 0.2 - 0.3 Gyr and a mass M = 0.09 MΘfor this archetypal late M-dwarf.
