Abstract (from CDS):

We present near-infrared spectroscopy of low-mass companions in a nearby triple system HD 130948 (Gliese 564, HR 5534). Adaptive optics on the Subaru Telescope allowed spectroscopy of the individual components of the 0".13 binary system. Based on a direct comparison with a series of template spectra, we determined the spectral types of HD 130948B and C to be L4±1. If we take the young age of the primary star into account (0.3-0.8 Gyr), HD 130948B and 130948C most likely are a binary brown dwarf system.
