Two stars scattered their remains after they came across each other. Fabulous news, the splendid celestial show can be seen with our own eyes! A dying star expanded outward in the “red giant” phase before it begins its inevitable collapse.
When the start riched its “red giant” phase, it attracted a smaller star toward itself. The lower mass of the star started to a beautifully spiral towards the red giant. This process caused the ‘little’ star to bring its evolution to a halt as it emits its outer layers ahead of time.
We can see the death process of HD 101584 supergiant with the help of the Atacama Large Millimeter/submillimeter Array (ALMA), an astronomical interferometer of 66 radio telescopes.
“The star system HD 101584 is special in the sense that this ‘death process’ was terminated prematurely and dramatically as the giant engulfed a nearby low-mass companion star,” said astronomer Hans Olofsson of the Chalmers University of Technology in Sweden.
Dying Star engulfed its low-mass companion
The star that spiral toward the red giant stopped approaching it right before the crash, which caused the red giant to erupt before its time, blasting its ejecting gas layers furiously. The process left behind a beautiful complex nebula of the smaller star remains.
Two jets explode from the red giant’s poles. They blew into the already ejected gas and dust, creating rings of gas in the process.
“Currently, we can describe the death processes common to many Sun-like stars, but we cannot explain why or exactly how they happen,” said astronomer Sofia Ramstedt of Uppsala University in Sweden.HD101584 gives us important clues to solve this puzzle since it is currently in a short transitional phase between better studied evolutionary stages.”
“With detailed images of the environment of HD101584, we can make the connection between the giant star it was before, and the stellar remnant it will soon become,” she added.
