What is the absolute magnitude of cassiopeia?
Cassiopeia is a constellation, not a single star, so it does not have a specific absolute magnitude. The stars within the constellation Cassiopeia have a range of absolute magnitudes depending on their distance and luminosity.
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
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.
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.
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)

Does the star Vega produce more light than the Betelgeuse star?
No. Check the absolute magnitudes, for example in Wikipedia or in Wolfram Alpha. The LOWER numbers refer to a HIGHER brightness (for visible magnitude) or total power output (for bolometric magnitude).
What is the absolute magnitude of the Milky Way?
An estimation of the absolute magnitude is −20.9. See related question.
Explain why size is the only factor that determines the stars absolute magnitude?
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
