Q:

What is a burnt-out star called?

A:

Quick Answer

A burnt-out star is called a white dwarf. A white dwarf results after a star’s nuclear fuel burns out, which causes it to collapse or implode. While it has a mass similar to that of the sun, its radius is similar to that of the Earth.

Full Answer

Studies by astronomers at the University of California, Los Angeles and University of Kiel, Germany, led to the conclusion that the formation of a white dwarf takes billions of years and progresses through a "red giant" phase. Further degeneration of the red giant leads to the death of the star, transforming it into a white dwarf.

  • Q:

    What is a low-mass star?

    A:

    A low-mass star, like the sun, is a star that was created by the gravitational collapse of large molecular clouds. The collapse of these clouds causes the matter to be pulled through a disk-like center, which eventually forms into what is called a protostar.

  • Q:

    What is the farthest star from Earth?

    A:

    Scientists will never know the farthest star from Earth, as the star is so far away that its light has not, nor will ever, have enough time to reach Earth. Even the stars within the visible universe are far too numerous to count, but the farthest one that humans have ever detected is about 55 million light years away. This incredibly distant star is called SDSS J 122952.66 +112227.8.

  • Q:

    When does a protostar become a star?

    A:

    When the temperature of a protostar rises higher than 10,000,000 K, it becomes a true star. At this temperature, hydrogen fusion begins to happen. Fusion heats the star, contracts the core and causes the star to emit light. A protostar must have 0.08 solar masses to become a star.

  • Q:

    What makes an ordinary star become a red giant?

    A:

    A star becomes a red giant when its internal fuel supply of hydrogen starts to deplete, causing its core to collapse. Hydrogen continues to burn in its expanding outer layers at a cooler temperature, giving it a red color compared to other stars.
