In the center of the Milky Way, stars younger than they need

The stars close to the center of our galaxy may almost never die because they raise darkest thing for strength.
More than two decades ago, astronomers noticed something strange in the stars near the center of the Milky Way center. First, the light they release suggested that they are younger than expected to be based on their mass, a problem is called “Karsox of Youth“. Second, older stars are not usually in this region, an issue called” Conundrum of old age “.
TODAY Isabelle John In Stockholm University in Sweden and his companions using a computer simulation to show that darkest thing can help solve two puzzles.
the Galactic Center Known to be more popular with dark matter, so researchers sucks the happens when a dark fragment object is hit by a star. They know that each particle lost energy and trapped inside the star when it collides with the nuclei of star atoms. If other particles in the black object have been tied to the same place, they concluded the destruction of each other, and every destruction makes a blast of energy that makes the star more vigorous.
The reason Stars at the age So they ran out of fuel for nuclear fusion, but the dark thing can be an extra energy source that gives life to a star. In fact, there is a darker thing near the Galactic Center that this process is effectively able to make stars without death, says John.
He said that the simulation of his team is very dependent on common thoughts about the dark matter and qualified equivalent to previous observations. But the real-world data can go further. Collecting many telescope data and factoring new findings about the dark matter, which is not well understood, helps determine what stars in the center of the Milky Way actually live forever.
Marc Pinsonneault In Ohio State University says it is also important to think about what the simulations mean for stars away from the Galactic Center. We have detailed data observation about stars closer to the ground, so any predicted effects of the dark matter should also check with this data, he says.
