Blue Stragglers :: essays research papers

Blue StragglersScientists establish of late rear that odd dealers known, as blue stragglers may be the product of striking between two, and possibly more, older aces. This may result in decision out a 50 year-old mystery of the blue stragglers.Even in dense aras stars a typic altogethery billions, if not, trillions, of miles apart. But stars may wealthy person the occasional chance to collide in international clusters, which are dense groupings of up to a million stars wit tightly packed cores. Some global clusters are among the oldest structures in the universe, about 15 billion long time old, all the stars in the clusters are known as red giants that have whiff up to there outermost atmospheres. In these clusters the presence of blue stragglers have baffled astronomers since the 1950s. Each of these stars less than a billion years old.Scientist recently realized that the collision of the older stars in the clusters could merge together to contrive one young one. Becaus e of the stars mass a color determining the geezerhood of the star. Red being cool, blue being hot. Heavy stars burning fast, luminosity stars undergoing a slow burn.Blue stragglers appear to be formed by the collision of stars known as main sequence turnoff stars. These are stars that have reached the end of their lives and are about to become red giants. quad of the Five blue stragglers examined were just the mass the astronomers expected had two stars collided. The ordinal was so much heavier than expected that Saffer, C. Rex, of Villanova University, suspects that three or more stars collided from it. When astronomers have made a computer model, and one scenario is that a lighter star crashes into a heavier one at 500,000 miles per hour, leaving behind a grand wake. Then buries itself at the core of the larger star, setting up broad shock waves on the stars surface. The newly formed, combined star can take anywhere from hundered of thousands of years to ten million years t o settle down into a new, stable star.
