The Milky Way's central supermassive black hole may be to blame.
Sixteen of these so-called"S-stars" — named after the black hole — are very young and are tens of times more massive than our sun. statement
."They couldn't have migrated to this region in just six million years, but to have a star form in such a hostile environment is surprising." Chu's team was searching for spectroscopic binaries. Sometimes, not even our best telescopes can resolve a binary system into two individual stars. In such cases, the only way to distinguish the components is by looking at their combined spectrum and observing a Doppler shift in the light caused by the stars orbiting around one another.
However, Chu's team found that none of the S-stars are binaries — all of them are singletons, confounding expectations that massive stars usually form in binary or even triplet systems. From their observations, Chu and his colleagues were able to place an upper limit on the fraction of binaries around Sagittarius A* as being 47% at most, far lower than in our sun's neighborhood.
"This difference speaks to the incredibly interesting environment of the center of our galaxy; we're not dealing with a normal environment here," said Chu.
