Question C:
... The easy way is to look up B−V=−0.30 for a B0V star in table A4-3, so B=2.5−0.3=2.2. The hard way is to first get the temperature of a B0 star from Figure 13-6 (25,000K), and calculate B−V=−0.52 using Equation 11-11a (although it is not meant for such hot stars). c. (5 pt): In a certain star, hydrog ...
