What is the apperant magnitude of Sirius?
Sirius is actually a binary star system. Sirius A has an apparent magnitude of -1.46 whereas Sirius B has an apparent magnitude of 8.3
Is Sirius a a white dwarf?
No, but Sirius B is,
How far apart are Sirius A and Sirius B?
Sirius is a binary star system Sirius A and Sirius B.The distance separating Sirius A from B varies between 8.1 and 31.5 AU. (See related question).
Where is Sirius b located in the night sky?
Sirius, which consists of both Sirius A and Sirius B is in the constellation Canis Major, which, if you are looking south, appears below and to the left of Orion. Sirius B itself is too dim to be seen from Earth; the vast majority of the light from Sirius is from Sirius A. Even then, as a binary system, the two stars are too close together for us to see them separately.
What is the final stage for Sirius b?
Sirius B is already a white dwarf. The next transformation will be to become a black dwarf, but not for many many years.
What is the apperant magnitude of Sirius?
Sirius is actually a binary star system. Sirius A has an apparent magnitude of -1.46 whereas Sirius B has an apparent magnitude of 8.3
What is the magnitude of Capella?
Capella (Alpha Aurigae) is the brightest star in the constellation Auriga.Although it appears as a single star, it is in fact a pair of binary stars. The primary pair are listed here.Capella A - Absolute magnitude: +0.35Capella B - Absolute magnitude: +0.20Capella A - Apparent magnitude: +0.91Capella B - Apparent magnitude: +0.76See related question for the difference.
What is Sirius?

What is a measure of the amount of a stars light that is received on earth A. absolute magnitude B. Apparent magnitude C. fusion D. parallax?
B:See related question;
Which stars always have large positive absolute magnitude?
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
Why is absolute magnitude of some stars greater than their apparent magnitude for stars?
The apparent magnitude is what we see, and this can be measured directly. The absolute magnitude must be calculated, mainly on the basis of (1) the apparent magnitude, and (2) the star's distance. So, to calculate the absolute magnitude, you must first know the star's distance.
Which is brighter Procyon or Gomeisa?
Procyon is a binary starProcyon A has an apparent magnitude of +0.34Procyon B has an apparent magnitude of +10.7Gomeisa has an apparent magnitude of +2.89So Procyon A is brighter than Gomeisa but Procyon B is dimmer.
How bright is Situla?
Kappa Aquarii (Situla) is a binary star in the constellation Aquarius.Situla A has an apparent magnitude of +5.04Situla B has an apparent magnitude of +8.8
Which star is brightest A Nova B White dwarf C Main-sequence D Red giant?
Brightness of a star is defined as apparent magnitude or absolute magnitude. (See related question).However, apparent brightness is affected by a stars luminosity and it's distance from Earth. So a very luminous star that is a long way away, will appear dim from Earth.Also from a factual point, a Nova is not a star but an explosion on a white dwarf.Apparent Magnitude (Today)C: The SunD: ArcturusB: Sirius BA: Short lived and depending on distance from the Earth, Could be brighter than D:Absolute Magnitude:C: R136aD: WOH G64A: (Depending on brightness it could be ahead of "D"B:
Is Sirius brighter than the sun?
Yes it is much bigger.Probably 5 suns can fit in sirius.Not only is sirius bigger but it is much hotter as well.
What is the radius of Sirius?
Sirius is actually a double star system consisting of two Stars - Sirius A and Sirius B. The mass of Sirius A is 2.02 solar masses (4.018 x 1030 kg).The mass of Sirius B is 0.978 solar masses (1.945 x 1030 kg).
Is Sirius a a white dwarf?
No, but Sirius B is,
