This was obtained using the CalcTool luminosity converter. Using the apparent magnitude of HIP 11915 and its distance from Earth (using the uncertainty parameter of ±10 light years), this yields a range of 1.03–1.27 L☉. When used in the default 190 light-year distance (with margin of error) is 1.07+0.11 −0.09L☉. When run into simulations using the orbital distance of HIP 11915 and its planet, yields a result of 118 K.
