There are many stars in the universe. Constantly there are new stars that are being born. A number of them are like the Sun, which is a medium-sized star. There are stars though more massive than the Sun, which scientists are curious of. How are massive stars born? Here's the answer to it, as a new study has shown.
The birth of massive stars is still largely a mystery. Dr. Rolf Kuiper, one of the researchers from the Institute for Astronomy and Astrophysics at the University of Tubingen and the leader of the Emmy Noether Research Group for Massive Star Formation, said that when they are being formed there is an opaque envelope of dust and gas that surrounds it, making the star hard to observe.
In order to make a more detailed study of it, the researchers have made a numerical simulation as a model for its formation process. High-performance computers were used to render this simulation. This has been made in order to make the process of the star's formation much clearer.
As with most stars, the formation begins with an accretion disk in which gases and dust swirl around it. These gases and dust continue to rotate around the forming star. As the gases and dust rotate around the star, slowly they fall into the star itself. As they fall, they form into clumps with high density. These clumps serve as fuel for the young star, as Dr. Eduard Vorobyov from the Institute for Astrophysics at the University of Vienna explained.
As these clumps fall, they then make the star burst with an intense luminosity, according to the University of Tubingen's site. It has been noted that this formation is almost similar to how stars of lower mass are formed. Dr. Dominique Meyer, the first author of the study, said that this formation is the common DNA for star formation that has been established since the formation of the universe.
With this study, astronomers can have a better way of knowing how to observe the luminous outbursts, as Science Daily reports. This could also help in getting the first images of these clumps as they fall into the young massive star. With the study, it would become clearer how massive stars have been formed.
The recent study tries to tackle the issue, how are massive stars born? Here's the answer to it, as the study points out that these massive stars are formed with accretion disks that have gases and dust clump together to feed to the growing star. If stars are born, they also die, and there is now an attempt to capture the first image of a black hole.
