In a 4.5 billion years of maturity, a object is still shining. In about 10 billion years, a Sun’s core will remove a lot of hydrogen and helium, branch it into a red hulk star. At slightest we’re all training in high school, right? Obviously, this does not explain a whole story.

A new study published on Monday in “Natural Astronomy” provides some-more sum on a ideas that existed before, about what happens when a object dies.

According to this study, a object will turn a scary expanding gas ring famous as a planetary nebula.

Professor Albert Zijlstra of a University of Manchester explained in a statement: “When a star dies, it sends a lot of gas and dirt – called envelopes – into space.” “An pouch can strech half a mass of a star. Revealed a core of this star, in a star’s life, this indicate has tired a fuel, and finally died before closing. ”

By building a new stellar data model, a group attempted to tract a final function of a sun. The indication predicts a liughtness of a solar heavenly effluvium formed on a age and liughtness of other stellar gas envelopes.

Although scientists had prolonged suspicion that a object wasn’t large adequate to form a heavenly nebula, a group showed that it was indeed a possibility.

The team’s indication shows that stars like a Sun, nonetheless reduce in mass than many other stars, can fast feverishness adult even when they die. This means that a object is still means to evacuate gas and dust, combining a manifest heavenly nebula.

“We found that stars whose mass is reduction than 1.1 times a mass of a object furnish a darker nebula.

The mass of a star is heavier than a effluvium whose solar mass is brighter, though a rest of a likely liughtness is really tighten to what was observed,” adds Zijlstra. .

Can this solve a long-standing discuss about a death of a sun? Incomplete, we mean, this is only a study.

This means that during slightest we have some convincing ideas about what happens when a favorite object dies during a final notation – it can turn a ghost.
