New analysis shows Betelgeuse erupted and is still recovering.
Republica.co.id, Nation World News – Betelgeuse looks bleak in 2019. Now a new analysis reveals why: Betelgeuse exploded and is still recovering.
About 530 light-years from Earth, the red supergiant is the brightest star in the night sky. This star forms the shoulders of Orion (the hunter).
This is also geriatrics. Betelgeuse is about to end its stellar life and will eventually explode into a supernova visible from Earth. However, according to the 2021 study, it could be another 100,000 years.
At the end of 2019, Betelgeuse’s lights began to dim. By February 2020, it had lost two-thirds of its normal brightness as seen from Earth.
Scientists studying the strange dimming have concluded that the star won’t go supernova anytime soon, but a huge cloud of dust obscures some of the star’s light. Now, as ScienceAlert reported on Monday (August 15, 2022), scientists using the Hubble Space Telescope have discovered that these dust clouds are the result of massive ejections from the star’s surface.
More than 1 million miles (1.6 million kilometers) of plumes can rise from inside stars. In a paper published in the arXiv preprint database, the team reports that this led to the equivalent of a stellar earthquake, an impact that blew up a small patch of the star’s surface larger than what is typically seen in the sun’s coronal mass ejection. 400 million times. And accepted for publication by D. Astrophysical Journal.
“Betelgeuse continues to do some very unusual things; the interior looks like it’s rebounding,” study author Andrea Dupri, associate director of the Harvard and Smithsonian Center for Astrophysics, said in a statement Say.
This is uncharted territory for stellar science, Dupri said.
“We’ve never seen this much mass on the surface of a star,” he said.
“We’re left with something we don’t fully understand. It’s a completely new phenomenon, and we can look directly at Hubble and study the details of the surface. We can see the evolution of stars.” Watch real-time,
