For the initial instance, astronomers have uncovered a ring of particles and debris surrounding a youthful star in a separate galaxy, labeling it a “significant occasion.”
A group of global specialists, led by Durham University, announced the discovery of a star and its spinning disk formation beyond our own galaxy, approximately 163,000 light years away from our planet.
The occurrence was witnessed in N180, a region within the Large Magellanic Cloud galaxy where numerous new stars are currently being created.
The accretion disc is a structure that is created when elements like gas, dust, and debris are pulled towards a developing star by gravitational forces.
The occurrence, published in the scientific journal Nature, was observed utilizing the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.
Dr. Anna McLeod, the main researcher from Durham University’s Centre for Extragalactic Astronomy, stated that upon initially observing the rotating structure in the Alma data, she was in disbelief that they had discovered the first extragalactic accretion disc. It was a moment that held significance for her.
“We are aware that disks are crucial in the process of star and planet formation within our own galaxy. This is the first instance in which we have observed concrete evidence of this phenomenon in a different galaxy.”
The astronomers were able to detect the presence of the disc by tracking the motion of the compact gas surrounding the star.
The speed of rotation of the disc is greater near the center compared to the outer edge. Scientists believe this varying speed is definitive evidence of an accretion disc.
Scientists estimate that the star is significantly larger, weighing approximately 15 times more than our own Sun.
According to scientists, it can be difficult to study large stars in our galaxy due to their frequent concealment by dusty matter.
The substance that gives rise to new stars in the Large Magellanic Cloud is fundamentally distinct from the substance found in the Milky Way. This provides astronomers with a clear perspective on the process of star formation.
The team explained that investigating the creation of stars and discs in various galactic settings will provide insight into the process of star formation.
Dr McLeod expressed enthusiasm for the opportunity to study the formation of stars in a distant galaxy.
