KOMPAS.com – When a bintang massive reaches the end of its life, will explode in a brilliant burst of light otherwise known as supernova. Telescope Hubble space NASA managed to find a star that survived a supernova event.
Using the Hubble Space Telescope’s Wide Field Camera 3, researchers were able to study supernova SN 2013ge in ultraviolet light. The light from bright star explosions or supernovae has been fading since 2016.
According to the scientists, other sources of nearby ultraviolet light have maintained their brightness over time, suggesting the star SN 2013ge has a surviving binary companion.
“This is the moment we’ve been waiting for, finally seeing evidence of a completely stripped-down binary system ancestor of supernovae,” said astronomer from the Space Telescope Science Institute in Maryland and lead researcher Ori Fox. SpaceThursday (12/5/2022).

Fox added, the research aims to see the actual system.
Using existing data, astronomers were able to identify signs of various elements in the ledakan supernova.
Surprisingly, no hydrogen was detected in the star region of SN 2013ge. Bintang Surviving this supernova explosion has scientists guessing how the gas could have been removed before the explosion occurred.
In addition, the observations help explain how some stars are stripped of their pre-supernova hydrogen, which is the result of a companion star sucking gas from its partner before exploding.
In recent years, mixed evidence has further strengthened that stripped supernovae may have formed in binary.

“But we haven’t really seen a companion. So much is studying cosmic explosions like forensic science, looking for clues and seeing what theories fit,” said Maria Drout, an astronomer on the team from the University of Toronto in Canada.
