Scientists made rapid progress in identifying ‘zombie’ stars that continued to burn after their core exploded. This finding is published in the Monthly Notices of the Royal Astronomical Society.
Launching the Daily Mail on Monday (07/08/2019), in the paper, the researchers said they managed to identify three rare and mysterious objects using data from the European space agency telescope, Gaia. Because it has good survival, the stars are given the nickname of zombies.
Two of the three stars were observed traveling at very high speeds across the Milky Way Galaxy. While the third star turns backward, moves in the opposite direction to the others.
Supernova’s zombie star
When several stars completely disappeared as soon as they reached the last reserve of fuel, they burst out in supernovae and released star material across the galaxy, some even got a second chance to live.
In new types of supernovae, it was found called the lax type and was able to disappear quickly. The researchers say the existence of zombie stars that are almost eliminated by their core explosion is theoretically possible.
By studying rare types of stars, scientists are likely to be able to learn about phenomena that lead to their creation, supernovae, closer. Supernovas, like zombie stars, are rare and often difficult to observe for astronauts because they can only be seen in distant galaxies.
By studying exploding stars, scientists say they can look closer as soon as possible after a supernova. In a report from Scientific American published before the new study, a researcher who was not affiliated with a paper studying zombie stars was similar to examining the remains of ancient dinosaurs.
The researchers hope that there will be at least 20 stars like those identified in this galaxy that can expand the scope of the data even further.
