The Eleven stars in the middle of our galaxy are living on the edge of a black hole. Investigators say they have found the group of stars, which are still forming, dangerously close to the super gigantic black hole at the heart of the Milky Way and it’s a remarkable find. Anything in the region of this black hole is supposed to be shredded away by the harsh situations it creates; scientists have examined the presence of young stars located strangely close in just three light-years away.
According to a declaration from the National Radio Astronomy Observatory Sagittarius A*, utilizing the Atacama Large Millimeter Array, or the Alma telescope, the investigators, detected signs of as many as 11 low-mass stars forming near the black hole. These budding-stage stars are nearly 6,000 years old and are in the developmental stage, a state in which they are no more a robust cloud of dust and gas but are yet to convert into a luminous, young star.
The surprising fact is that, at this distance, the tidal forces, ultraviolet light, and X-ray radiation is driven by the four million solar mass black hole should have exploded away the clouds of gas and dust well before they moved into the developmental phase, creating protostars. Remarkably noisy surroundings and powerful radiation from black holes like this are capable of disturbing the star formation process. Though, the presence of these protostars proposes that the conditions needed for star formation may exist even in some of the unfriendly regions of our galaxy and universe.
The lead author of the paper published in Astrophysical Journal Letters Farhad Yusef-Zadeh says that despite all odds, we saw the best evidence yet that low-mass stars are forming astonishingly close to the supermassive black hole at the center of the Milky Way. This is a genuinely unexpected result and one that describes just how strong star formation can be, even in the most strange of places.
The scientists recognized the protostars by seeing double lobes of material around each of them. These hourglasses like shapes signal the initial stages of star development and carry molecules like carbon monoxide which glow radiantly in millimeter-wavelength light, something which Alma can discover with remarkable accuracy and sensitivity.
It is yet unclear how these stars are building; cosmologists consider that external forces like high-velocity gas clouds or jets from the black hole itself could have supported in overcoming the violent nature of the area and activating the star formation. Al Wootten, the co-author of the paper, stated that though these situations are far from ideal, we can envision various pathways for these stars to appear.
