bolometric correction

(difference between an object's bolometric and visible magnitudes)

Bolometric correction is a difference in magnitude applied to stars to determine their bolometric magnitude from their visible magnitude. It varies by type of star, e.g., spectral type, and is largest for stars much hotter or cooler than the Sun because the EMR from stars of the Sun's temperature is centered around visible light. Some bolometric correction examples:

O3 star-4.3 for a main sequence star-4.2 for a giant
G0 star-0.10 for a main sequence star-0.13 for a giant
M0 star -1.21 for a main sequence star-1.28 for a giant
