B-v to temperature
WebIt has visual magnitude of -1.44, B-V of .009, and a parallax of 379.21 milli arc seconds. Finding its distance from its parallax yields d = 1/p = 1/.37921 = 2.63 parsecs. Its absolute magnitude is M = m - 5 log d + 5 = -1.44 - 5 log (2.63) + 5 = 1.46 We know the temperature of the Sun is 5800K. WebB - V = 0.7 - 0.9 = - 0.2 U - B = -0.24 -0.7 = - 0.94 Generally, the negative values of these color indices are an indication that Spica is a hot star, with most of its radiation coming at shorter wavelengths. On the other hand, for Antares B = 2.7 and V=0.9, and the B - V color index is B - V = 2.7 - 0.9 = 1.8
