bolometric magnitudeThe magnitude of a star measured across all wavelengths, so that it takes into account the total amount of energy radiated. If a star is a strong infrared or ultraviolet emitter, its bolometric magnitude will differ greatly from its visual magnitude. The absolute bolometric magnitude (see absolute magnitude) of a star is a measure of its total energy emission per second, or luminosity. The bolometric correction is the visual magnitude of an object minus its bolometric magnitude.
