Before the star Cassiopeia A exploded in a supernova, something had already come by and stripped it bare.<\/p>
The clouds of gas expelled by the supernova, Live Science<\/a><\/em> reports<\/a>, are missing hydrogen, which usually forms the outer layer of a star while heavier elements stay toward the core. Now, scientists think they know why: Cas A may have been too close to the earlier supernova of its neighbor, an explosion that would have been strong enough to blow the hydrogen layer away.<\/p> An international team of astronomers modeled how when one star in a binary system blows up<\/a>, it can essentially “sandblast” the other one, as Live Science<\/em> put it. Their research<\/a>, published in the journal Monthly Notices of the Royal Astronomical Society<\/em>, matches the existing data on what happened to Cas A and similar binary supernovae.<\/p> “This is enough for the second supernova of the binary system to become a stripped-envelope supernova,” lead author Ryosuke Hirai, a researcher at The Australian Research Council Centre of Excellence for Gravitational Wave Discovery, said in a press release<\/a>, “confirming that our proposed scenario is plausible.”<\/p> The first supernova taking away Cas A’s outer layer of hydrogen also likely sent it into a wildly unstable state, Live Science<\/em> reports, potentially speeding up its own death.<\/p> The new research is only a model. But just as those models predicted, the researchers found a cloud of hydrogen 50 lightyears away: a shattered remnant from the first explosion.<\/p> Editor’s note 10\/7\/2020: An earlier version of this story misstated Cas A’s distance from Earth.
