A new study led by researchers from Australian National University takes a closer look at a cosmic phenomenon that slows down the energy-intensive process of star formation to pave the way for life in a galaxy.

The team studied the process where stars give a counter pressure to gravity that slows down the process of star formation, Dr Roland Crocker, leads researchers from the ANU research school in astronomy and astrophysics, told the university press.

“If star formation occurred quickly, all stars would be tied into massive clusters … where intense radiation and supernova explosions were likely to sterilize all planet’s systems, preventing the emergence of life,” said Crocker.

“The conditions of these massive star clusters can even prevent the formation of planets in the first place.”

The researchers discovered that the majority of the process is influencing the oven of light in different forms of energy. Ultraviolet light and visible light from large newborn stars hit the remaining cosmic dust in the space surrounding a newly formed star.

Infrared light is also spread by this remaining cosmic dust that activates the air surrounding the newborn star and acts as a back pressure against the star’s gravity.

“The phenomenon we studied occurs in galaxies and constellations where there is very dusty gas that forms a lot of stars relatively quickly,” says Crocker.

“Galaxies form stars slower – like Winter Street – other processes slow down things. The winter street forms two new stars each year, on average. “

Astronomer accepts that all galaxies in the universe form new stars continuously and at a steady rate. The new study found a mathematical upper limit for how fast stars can be formed in a galaxy or gas-giant cloud. The counter pressure and capability of star formation in galaxies are some of the feedback mechanisms as a star system must keep the universe alive and alive, according to Crocker.

“We explore other ways that stars can reconnect to their environment to slow down overall star formation.

The study was published in the journal Monthly Announcements from the Royal Astronomical Society .
