Absolute magnitude is the brightness of an object (star, galaxy, etc.) from a standard distance."Bolometric" means that the entire energy output is calculated - not just visible light.

What is absolute magnitude of Rigel?
Its absolute magnitude is -7.92
What is the absolute magnitude of Betelgeuse?
The absolute magnitude of Betelgeuse is -6.05
What is the absolute magnitude of cassiopeia?
Cassiopeia absolute magnitude is 2.20 to 2.23
What is the suns absolute magnitude from earth?
You cannot ask for an absolute magnitude and specify the distance, as the absolute magnitude is derived from a set distance of 32.616 light years.At that distance, the absolute magnitude of the Sun is +4.83From Earth the apparent magnitude -26.74
Are absolute magnitude and apprent magnitude the same thing?
No. Apparent Magnitude is what it looks to be, whereas absolute is its actual mangnitude.
Which magnitude gives the most information about the physical nature of a star?
absolute bolometric magnitude
Why does Bellatrix has the brightest absolute magnitude?
The simple answer is that it does not. It is important to note that stars radiate across a whole range of electromagnetic frequencies, not just in the visible part of the spectrum. Astronomers use bolometric absolute magnitude to adjust for the fact that a star may be radiating much of their energy outside of the visible range. Using the bolometric absolute magnitude, the brightest star, with magnitude -12.5 is RMC136a1 in the Large Magellanic Cloud, at a distance of 163000 light years.Among stars visible to the naked eye, Bellatrix does not even make it to the top ten in terms of its bolometric absolute magnitude. That distinction goes to P Cygni with an absolute magnitude of -9.7. It is 5900 light years away. In comparison, Bellatrix has a magnitude of only -2.64
I am given the bolometric BC equals -1.46 and the visual magnitude V equals 4.33 of a star. how do you calculate the angular diameter?
The bolometric correction allows you to convert between visual and bolometric (total) magnitude - where the bolometric magnitude includes all radiation emitted by the star, not just visible light. It has nothing to do with the angular diameter.
What body in space is the most luminous star?
The most luminous star in space is named R136a1 which is 160,000 light years away from space. It measures absolute bolometric magnitude of -12.6 , and an apparent visible magnitude of 12.84.
Which star has the largest absolute magnitude?
There is a star in the Large Magellanic Cloud called R136a1 which has an absolute magnitude of -12.5. Undoubtedly others will turn up as time goes by. M33-013406.63 in the Traingulm Galaxy has an absolute magnitude of -12.2 to -12.7 (not quite sure of the exact M)
