Context. We have already imaged a co-moving companion at a projected separation of ∼260 AU from the young star AB Pic A. Evolutionary model predictions based on JHK photometry of AB Pic b suggest a mass of ∼13−14 MJup, placing the object at the deuterium-burning boundary. Aims. We aim to determine the spectral type, the surface gravity, and the effective temperature of AB Pic b. From the comparison of our absolute photometry to surface fluxes generated by atmospheric models, we also aim at…
