1. The problem statement, all variables and given/known data A binary star system at a distance of 85pc consists of two stars of equal luminosity that are so close together that they are observed in a telescope as a single image. If the apparent magnitude of the two stars combined is 10.7 what would be the apparent magnitude of just one of the component stars? 2. Relevant equations m= -2.5 log(L) m-M=5log(d)-5 3. The attempt at a solution I think I need to figure out what the two luminosities are added together?
