A New Star Around the Galaxy's Central Black Hole.
This new star was recvently found using the Keck telescope in Hawaii. It is now the fastest moving star to obrit the black hole. Taking a total of 11.5 years (give or take a few months). Out orbiting the S0-2 which takes about 16 years. The main reason the S0-102 evaded discover is because it is 16x fainter than the S0-2.
With this newly found star the scientists can now study Einstines' Theory of Relativity in an extreme environment. By having two short-period stars allows astronomers to look into the change in orientation (precession) of the orbits over time. This teaches them how much space has ben curved by the gravity of the black hole (about 4 million times the mass of the sun). Knowledge of the orbiting paths of the orbital period of the stars help astronomers model the black hole and test the general relativity of the region closest to the hole. Currently the stars' motion is modeled using Newtonians Physics and Keplar's Laws to a exceedingly high degree of accuracy. (shown above)
