Real star wars! Beautiful image reveals the aftermath of a ‘FIGHT’ between a red giant and a smaller star
- New research examines a violent collision between two distant stars
- The nebula was formed when a red giant tried to flood a smaller star
- Instead of being submerged, it almost crashed into the core of the red giant
- The gases were then emitted and left drifting in the mist
Sometimes losing is inevitable, even if you fight well.
Published in a new study in Astronomy & Astrophysics using observations from the Atacama Large Millimeter / submillimeter Array (ALMA), researchers show the aftermath of two stars that go toe-to-toe.
According to them, gases in mist HD101584, a strange and complex-looking amalgam, were formed from the tumult of when one star, a red giant, a smaller companion engulfed.
With newly captured images and analyzes, scientists now say that the cloud was made when the main star of the system was blown up into a red giant and eventually large enough to swallow its lower-mass counterpart.
In Alma’s observations (photo), gases emitted by the stars can float around the nebula in a complex and strange series. Colors, different gases, also represent speed, where blue is the gas that moves to us the fastest and the gas that moves further
However, instead of being completely engulfed by the expansion of the star, the smaller star wriggled toward its larger companion core, but failed to collide.
Instead, the movement has prompted the larger star to expel its gas, exposing its layers scattered throughout the system and its core.
“The HD101584 galaxy is special in the sense that this” death process “was prematurely and dramatically ended because a nearby low-mass star was flooded by the giant,” said Hans Olofsson of Chalmers University of Technology, Sweden, who led a recent study , published in Astronomy & Astrophysics
According to researchers, the violent collision created the complex structure of gases in the HD101584 nebula, especially the spiral of the smaller star toward the red giant in addition to the gas jets that formed in this process.
Those rays radiated through the previously ejected material and formed the gas rings and the clear bluish and reddish spots seen in the mist, they say.
The nebula is located in the Centaurus constellation, which is circled above, and is close enough to observe gases using ALMA, but none of the stars buried inside
‘We can currently describe the death processes that many sun-like stars have in common, but we cannot explain why or exactly how they happen. HD101584 gives us important clues to solve this puzzle, as it is currently in a brief transition phase between better studied evolutionary stages, “said co-author Sofia Ramstedt of the University of Uppsala, Sweden, in a statement.
“With detailed images of the environment of HD101584 we can make the connection between the giant star it used to be, and the stellar remnant that it will soon be.”
In addition to clarifying the interaction between stars at their death stage, researchers say that the insight also helps to understand how our own sun, which is a red giant, can extinguish.
Likewise, the sun is expected to expand slowly and to flood gases and materials in its path, although this is not expected to occur for another 5 billion years.
