What happens when the sun looses enrgey?

The sun enrgey goes in the white dwarf and the sun becomes a giant bright star then it is.


Is nova a bright star?

No, a nova is not a star itself, but rather an astronomical event that occurs on the surface of a star. A nova is a sudden, temporary increase in brightness caused by the explosion of material on the surface of a white dwarf star.


What happens to a star when it becomes a super giant?

Some do, some become "bright giants" instead.


How did the TV Show Nova get its name?

The name "Nova" is used in two senses, both because Nova is a science program. Nova means "new" in its original sense and was later adopted by astronomers to describe a bright, exploding star.


What is it called when a star becomes brighter as a result of a sudden explosion?

Once a star explodes, it's no longer a star. The explosion itself is referred to as a "Super Nova."


What causes the sun to be a star?

How can you use the word nova in a sentence?

This refers to a star near the end of its life. Here are some sentences.The astronomer studied the nova.The star suddenly flared brightly; it had gone nova.A nova often collapses into a black hole or a white dwarf.


What is an explosion seen when a white dwarf captures H from a companion star?

When a white dwarf star accretes hydrogen from a companion star, it can trigger a runaway nuclear fusion reaction that causes a sudden and bright increase in brightness called a nova. This explosion is not as powerful as a supernova, and the white dwarf usually survives to potentially experience multiple nova events.


Has there ever been a record of a star that popped in the sky as a new star?

Yes, this has happened several times. However, it isn't a NEW star, but an old one dying. During the middle ages, some observers would rarely observe a star, sometimes quite bright, appear where no star had been seen before. They called this a "nova stellarum", or "new star". Typically, the "nova stellarum" would be visible for several weeks and would then fade from view. In one case, the "new star" was so bright as to be visible during the day! We now know that this "nova" wasn't a NEW star; it was a titanic explosion of an old star that had been too dim to be visible, blowing itself apart.


What happens as gravity increases to the pressure on the matter within a star?

As gravity increases so the pressure within the star increases, the matter becomes more dense and hotter, more matter is fused. The star decreases in volume initially. The thermal pressure increases to maintain equilibrium.Depending on the total mass the star may then expand to a giant or 'explode' catastrophically as a nova.


What happens to a star in a close binary system when it becomes a giant?

When a star in a close binary system becomes a giant, it can transfer mass onto its companion star through an accretion disk or stellar wind. This can cause the companion star to gain mass and potentially also evolve, affecting the dynamics of the binary system. The end result can be a variety of outcomes, such as a common envelope phase or even a merger of the two stars.
