Cooler companion

15 Sagittae B, also Gliese 779 B and HR 7672 B, is probably substellar L dwarf. Its spectral type is estimated to be ± 1.5 L6 and using models is a mass of about 60 to 70 Jupiter masses derived. Under certain assumptions, the effective temperature is estimated to 1510-1850 K. The angular distance from the central star is 0.79 ", which projected a distance of about 14 astronomical units corresponds. The object was discovered in 2002 by Liu et al. Mauna Kea Observatory.
