L(HV) = 2.03 x 10^(31) W L(Sun) = 3.83 x 10^(26) W So the absolute magnitude of the HV system can be calculated as 2.03 x 10^(31) (abs mag HV) = (abs mag Sun) - 2.5 * log10 ( -------------- ) 3.83 x 10^(26) = 4.83 - 11.81 = -6.98 But if we include a bolometric correction of BC = -2.4 mag, we find (abs mag HV) = -6.98 - (-2.4) = -4.58 The apparent magnitude to HV 2274 is (app mag = 14.16). distance modulus = (app mag) - (abs mag) = 14.16 - ( -4.58 ) = 18.74 This corresponds to a distance to HV 2274 and the Large Magellanic Cloud 0.2 * ( [m-M] + 5 ) distance = 10 = 56 kpc
