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.


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.


Is Sirius a medium mass star?

Yes, Sirius is about twice as massive as our sun, making it a medium mass star. It is quite a bit brighter, however, and is the second brightest star in our sky.


Does B Sirius cause Sirius A to wobble?

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.


Will Sirius become a supernova?

Sirius A does not have enough mass to become a supernova. It will end it's life as a white dwarf.


What is the celsius temperature of Sirius?

Sirius is a binary star. The temperature of Sirius A is roughly 10,000 degrees and Sirius B is about 25,200 degrees. These are only rough estimates as it is extremely hard to measure the exact temperature of something so hot


What is the life and death of Sirius the star?

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.
