Does it mean that the star is a main sequesnce star? ( . Y . ) The above isn't true. A star can be a blue supergiant and be on the main sequence but still not be even visible to us, therefore the apparent and absolute magnitude wouldn't be the same. But to answer your question, I don't think it has a name, it just means that you are seeing the star's absolute and apparent magnitude at the same time, so if you placed the star at 32.6 light years away(the absolute magnitude scale)then the star would not appear to change in brightness
What else can I help you with?
Why does a star such as betelgeuse which is located far from earth have a much greater absolute magnitude than apparent magnitude?
well my reason is that the betelgeuse must be very large , because they said that the betelgeuse is located far from earth .

What is a large star of high luminosity?
A good example of a medium size star is the Sun, which is very average. Luminosity is measured by the star's absolute magnitude, which is the magnitude seen from a standard distance of ten parsecs (32.6 light-years), and the Sun's absolute magnitude is +4.7. A factor of 100 increase in luminosity corresponds to 5 magnitudes less (larger magnitudes mean dimmer stars). The brightest stars have absolute magnitudes around -7.
Why does the sun appear to be the brightest object in the sky?
The sun is the closest object to us that emits its own light. The moon and the five planets we can see at night all reflect light from the sun.It's closer to the earth and it has fireThe sun is the brightest object in the sky because, quite simply, it is the closest star to the EarthThe sun is the brightest object in the sky because for any object close to Earth (solar system), the Sun is the brightest by far.Though there are other stars in the universe hundreds of times brighter than our Sun, there are two factors that determine how bright a celestial object looks to us.1. Its' actual brightness (absolute magnitude)2. Its' distance away from us. The brightness as perceived by us decreases by the square of the distanceThe combination of these two factors result in the apparent magnitude, how bright a star looks to us.For example, the Sun has an absolute magnitude of 4.83 (the smaller the number, the brighter) while it has an apparent magnitude of −26.73.The star Sirius has an absolute magnitude of 1.42 which is brighter than the sun but has an apparent magnitude of only -1.46.This is due to the fact that the Sun is so much closer to the Earth.
How does the brightness of a quasar compare with that of a large galaxy?
I assume when you mean brightness, you mean apparent magnitude as opposed to absolute magnitude. The quasar 3C 273 has an apparent magnitude of about 12.8 whereas the brightest galaxy - the Large Magellanic Cloud has an apparent magnitude of 0.9. However, in absolute magnitudes, 3C 273 has an absolute magnitude of about -26.7 very similar to our own Sun.
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
How can two supergiant stars have an absolute magnitude of -3 but one has a radius of 10 times the sun and the other 100 times the sun?
The absolute magnitude of a star depends on the size and temperature; a large cooler star can generate as much light as a small very hot star.

What is the used to measure earthquakes?
The absolute magnitude of a quake is conventionally reported by numbers on the Moment magnitude scale (formerly Richter scale, magnitude 7 causing serious damage over large areas), whereas the felt magnitude is reported using the modified Mercalli intensity scale (intensity II-XII).

How do you measure absolute magnitude?
The absolute magnitude is the magnitude (brightness) an object would have at a standard distance - how bright would it look at a standard distance. For a star or galaxy, the standard distance of 10 parsecs is commonly used.
When was The Absolute at Large created?
The Absolute at Large was created in 1922.
What is the price of a larger cup of coffee at Tim Horton's?
The differences will not be as small as the person thinks them to be when they are checking at negative magnitude from one dollar and positive magnitude of one dollar
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)
What is simple definition of magnitude?
In simple terms, "Magnitude" means "Largeness". Magna is the root of magnitude, and means large.
