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 \farcs 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 \pm 1 .
If we take the young age of the primary star into account ( 0.3–0.8 Gyr ) , HD 130948B and C most likely are a binary brown dwarf system .
