  • We present J-band imaging and H+K-band low-resolution spectroscopy of 2MASS 1207-3932AB, obtained with VLT NACO. For the putative planetary mass secondary, we find J = 20.0 ? 0.2 mag. The HK spectra of both components imply low gravity and a dusty atmosphere for the secondary. Comparisons to synthetic spectra yield Teff,A ? 2550 ? 150 K and Teff,B ? 1600 ? 100 K, consistent with their late-M and mid- to late-L types. For these Teff and an age of 5-10 Myr, evolutionary models imply MA ? 24 ? 6… CONTINUE READING
