SUMMARY
The discussion centers on calculating the apparent magnitude of a single star in a binary star system with two stars of equal luminosity observed as a single image. Given the combined apparent magnitude of 10.7 and the distance of 85 parsecs, participants emphasize the need to utilize the logarithmic relationship between luminosity and magnitude. The formula m = -2.5 log(L) is crucial for this calculation, along with the logarithmic base of approximately 2.512 for combining magnitudes. The approach involves manipulating logarithmic values to derive the individual star's magnitude.
