The magnitude of a celestial body for all wavelengths. It is a measure of the energy emitted in all wavelengths per unit time.
The magnitude of a celestial object corrected to take account of the radiation in parts of the spectrum other than the visible. A to F | G to L | M to R | S to Z
The magnitude, apparent or absolute, of a star, taking into account all of its radiation, visible and invisible.
The total radiation received from an object.
See apparent magnitude or absolute magnitude.
The bolometric magnitude of a star includes the total radiation output of the star (not just visible light). It is the magnitude that a star would have if all of its energy were included in the measurement. It includes the entire electromagnetic spectrum: X-rays, ultraviolet, infrared, gamma rays, etc. The ordinary magnitude of a star only takes into account the visible light that the star emits.
