So do stars also sneeze? It seems as if it is raining sparklers, new research reveals


Star Sneeze: Scientists at Kyushu University have recently revealed in a new research that ‘baby stars’ or ‘protostars’ sneeze during their formation. Their sneeze discharges plumes of dust, gas and electromagnetic energy. They believe that this reveals a lot about the formation of stars.

When dense and cool patches of interstellar gas and dust gather into massive clouds, it is called a stellar nursery. All stars, including the Sun, are born in stellar nurseries, large concentrations of gas and dust. These nurseries gather gas and dust to form a stellar core or “baby star”. Some of this gas and dust forms a ring around the baby star, called a protostellar disk.

Talking about the sneezing of baby stars, Kazuki Tokoda, the author of this research, said, ‘Magnetic fields enter these structures, which causes magnetic flux in it, however, if all this magnetic flux remains constant then the star develops. In the journal, the researchers have studied MC 27, which is a stellar nursery. It is located about 450 light-years away from the Earth. This observation was taken with the help of 66 high-quality radio telescopes located in Chile.

Takoda said, ‘We found something different in our data analysis. There were ‘spike-like’ structures in the protostellar disk. These were spikes of dust and gas ejected from the magnetic flux. Such a phenomenon is called ‘interchange instability’, where protostellar disk instability in the magnetic field interacts with different densities of gases, resulting in a part of the magnetic flux being ejected.’

Tokuda said that we dubbed it the ‘sneeze’ of a baby star. It reminds us of dust and air being ejected very rapidly. After looking even a little further away from the protostellar disk, scientists discovered that these could be “sneezes” of other stars in the past.

Researchers hope this ‘sneeze’ can help them understand the complex processes of formation of stars, which can help shape the universe.
