Photometric spectral energy distribution of GJ7 (circles). The PHOENIX solar-metallicity model (T_eff = 3800 K, log g_∗ = 5.0 cm s⁻²) is shown by the gray line normalized to the observed fluxes between 0.8 and 1.6 μm (Husser et al. 2013). Photometric error bars are included, although for most of the wavelengths they have the size of the symbol. The horizontal errors account for the effective width of the filters. At short wavelengths, GJ7 exhibits flux excesses with respect to the photospheric emission indicative of some stellar activity, while at the longest wavelengths, there are no obvious infrared flux excesses. Both axes are on a logarithmic scale.
