It has been determined by astronomers that the dead star, called the “Tasmanian Devil”, located one billion light years away from Earth, is emitting energy into space, indicating that it is still active after it exploded.
After the first explosion of the “Tasmanian Devil” detected in September 2020, astronomers detected short, bright flashes as powerful as the explosion that caused the death of the star.
It was stated that the first explosion that caused the death of the star in question was not a typical “supernova”, which means an increasingly brighter star explodes and throws out most of its mass, but a rare type of explosion called “Bright Fast Blue Optical Transition (LFBOT)”.
It was stated that LFBOTs, which were first discovered in 2018, reach maximum brightness within a few days and fade out, while the supernova glow can last weeks or months.
The research included information that the LFBOT belonging to the “Tasmanian Devil” was named AT2022tsd and was observed with 15 telescopes around the world.
“Surprisingly, instead of steadily fading as expected, the source (the Tasmanian Devil) brightened repeatedly for a short time. LFBOTs are already strange, exotic events, but this was even stranger,” Anna Ho, a faculty member of Cornell University’s Department of Astronomy, said in a statement. “We have never seen a light this fast before in any supernova or ‘Fast Blue Optical Transit’ and its brightness months later is as strong as the first explosion,” he said.
