No. Sirius B is a white dwarf. It is the remnant of a star that used up its supply of hydrogen.
Sirius B is a white dwarf. As the name suggests, it will appear white.
Sirius's fate might be peaceful; just ejecting it's outer red giant layers to make a planetary nebula. It is 2.02 times the mass of the Sun. However, Sirius has a white dwarf companion. On Sirius B's death, Sirius A might have formed. At the other end, Sirius B might destroy Sirius A. White dwarfs have very strong gravity, and if it is close enough, Sirius B might steal material from Sirius A. When a white dwarf stealing mass from the parent star has enough mass to create iron, the iron triggers a Type 1a supernova. If this happens to Sirius B, Sirius A could either be destroyed by the immense force of the explosion, or become a runaway star, travelling faster than even Barnard's Star. If this is the case, Sirius A might eat smaller stars or crash and burn into a larger star. If it heads towards us if this happens, we would be doomed.
Sirius is a binary star system with two main stars, Sirius A and Sirius B. Sirius A, the brighter and more massive star, has a surface temperature of around 9,940°C (17,964°F). Sirius B, the smaller and fainter star, has a surface temperature of about 25,200°C (45,332°F).
Sirius is actually a binary star system.Sirius A is a type A1V star so has a colour of Blue White -> BlueSirius B is a white dwarf.
The flickering star in the eastern sky tonight is most likely Sirius, also known as the Dog Star. It is the brightest star in the night sky and is visible in the early evening in the eastern sky. Sirius is a binary star system, meaning that it is made up of two stars that orbit each other. The main star, Sirius A, is a white-hot star that is much brighter than our Sun. The companion star, Sirius B, is a white dwarf star that is much fainter than Sirius A. Sirius is a very hot star, with a surface temperature of over 10,000 degrees Celsius. This heat causes the star to emit a lot of light, which is why it is so bright. Sirius is also very large, with a diameter that is about twice the diameter of our Sun. Sirius is a relatively young star, with an age of only about 250 million years. This means that it is still burning hydrogen fuel in its core. Once Sirius runs out of hydrogen fuel, it will eventually become a red giant star. Sirius is a beautiful and fascinating star that is sure to amaze stargazers for years to come.
Like other stars, Sirius formed when a cloud of gas and dust called a nebula collapsed under the force of gravity. As the cloud collapsed it formed two masses that heated up until the nuclear fusion of hydrogen ignited, turning the two masses into stars by 200 to 300 million years ago. The result was a binary star system consisting of the smaller Sirius A and the larger Sirius B. Since Sirius B was more massive it burned through its hydrogen fuel more quickly and eventually exhausted its fuel supply. By about 120 million years ago it has shed most of its mass while the remainder collapsed into a small, dense remnant called a white dwarf, leaving Sirius A as the larger, more massive body. Sirius A has not yet finished its fuel supply and will likely last for about another 1.5 billion years or so.
It already has. Sirius B is a white dwarf, the dense remnant of a dead star. While it is no longer producing energy through fusion, Sirius B still glows with the leftover heat of when it was an active star. Because of the huge amount of heat and relatively small surface area, it will take trillions of years for Sirius B to cool.
No, but Sirius B is,
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).
Sirius B is a white dwarf. As the name suggests, it will appear white.
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.
It is not real. Sirius is a two-star system containing only Sirius A and Sirius B.
Sure - the two attract each other. In the case of a double star - as Sirius A and Sirius B - both revolve around their common center of mass.
Sirius B is a faint white dwarf companion of Sirius A It has an apparent magnitude of +8.3 and an absolute magnitude of +11.18
No. Sirius consists of two stars. Sirius A is larger than the sun but is not a giant. Sirius B is a white dwarf,
Neither Sirius A nor Sirius B have any known planets.
