What is star Sirius made of?
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.
Where can one go to buy a Sirius boombox?
A Sirius boombox may be purchased The Source, Future Shop or Best Buy. Some mass retailers such as Walmart or Target may also carry a few models of the Sirius brand boombox.
How many earth can fit in sirius?
Well, darling, Sirius is about twice the size of our dear old Sun, and the Sun could fit about 1.3 million Earths inside it. So, if we do the math (which I'm sure you could handle), Sirius could fit around 2.6 million Earths inside it. But hey, who's counting? Just know it's a whole lot of Earths.
How is a protostar created?
Sometimes. If the total mass is high enough, and if the cloud of dust and gas collapse to reach a high enough density and pressure, nuclear fusion can begin in the core and it will become a star. If the total mass is not high enough, it may collapse into a "brown dwarf".
What is a verdi piece?
Verdi is best known for his operas, including "Aida," "Macbeth," and "Ernani." He also composed a beautiful "Requiem" Mass
How does the the mass and size of a white dwarf compare with the mass and size of the sun?
A white dwarf, also called a degenerate dwarf, is a small star composed mostly of electron-degenerate matter. They are very dense; a white dwarf's mass is comparable to that of the Sun and its volume is comparable to that of the Earth.
Will Sirius become a supernova?
No, Sirius will not become a supernova. It is a relatively young star compared to those that typically go supernova, and its mass is not sufficient to trigger such an explosive event. Sirius is expected to eventually evolve into a white dwarf.
Is Sirius b a high or low mass star?
Sirius B is a white dwarf. So it is low mass compared to other stellar remnants.
You know the white dwarf stars Sirius B has a mass comparable to the Sun because of?
Because a white dwarf star is the core leftover from a bigger star and the core is the densest part of the star so although the star is smaller than the sun it has a similar mass as it is more dense
How large is a white dwarf?
A white dwarf is typically about the size of Earth, but with a mass comparable to that of the Sun. This means it is extremely dense, packing a lot of mass into a small volume.
What is the next stage in the life of a lower-mass main-sequence star?
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
What is the size and color of the star Sirius?
Sirius is actually a binary star system, which means there are two stars (A & B).Sirius A is 25 times more luminous that our Sun. It is estimated to be twice as large as our Sun.It is a type A star and is thus classified as a between Sub Giant and Giant.Sirius B is a white dwarf and has the mass of the Sun but the size of the Earth.Both stars are spherical in shape.
What is the size of a white dwarf compared to?
A white dwarf has the approximate diameter of a moon, or a small planet.
Is Sirius a low mass star?
It is, but at twice our suns mass, Sirius A is on the limit, of being an intimidate mass star. Sirius A will have a life cycle similar to that of our own star which is a low mass star, but burns hotter. Sirius B is a companion white dwarf star with a mass of around the same as our sun. Previously, it was thought to have been a star with a mass of around 5 times that of our sun, burning out more quickly than Sirius A.
What is the mass of a yellow dwarf star?
Our Sun is a yellow dwarf, so it's mass will be comparable. See related questions for the mass of the Sun
What is the mass of the yellow dwarf star?
Our Sun is a yellow dwarf, so it's mass will be comparable. See related questions for the mass of the Sun
Which of these has the smallest radius a 1.2 solar mass white dwarf a 0.6 solar mass white dwarf or Jupiter?
Jupiter is far larger than the other two. White dwarfs can be treated as Fermi gasses, and have the interesting property that as their mass increases their radius decreases. So the smallest is actually the 1.2 solar mass white dwarf.
