Recently, Hubble Telescope discovered a massive, fast-aging star with strange behavior, and has been named ‘Nasty 1.’ The star was discovered years ago, which was identified as Wolf-Rayet star, a massive-evolving star, larger than the Sun.
Astronomers have named the star as NaSt1 with the nickname ‘Nasty 1.’ Astronomers believe that the star loses hydrogen layers rapidly, resulting in the exposure of super-bright and blinding bright helium-based core. However, after a decade, the Nasty 1 does not resemble the Wolf-Rayet star. Lead researcher from the University of California, Berkerley John Mauerhan stated that they were excited to see the disk-like structure because it might be the evidence for a Wolf-Rayet star forming a binary interaction.
There are very few examples in the galaxy of this process in action because this phase is short-lived,” said Mauerhan.
The team came up with several scenarios for the age and formation of the star. However, the best theory indicates that the star is evolving rapidly due to the loss of hydrogen layers, causing it to swell. The observation is noticed in some stars, but it’s a rare occurrence in usual ones. Researchers believe that there might be only a few stars like Nasty 1, and is believed to be a few thousand years old, located about 3,000 light years away.
The long-term study involved extensive research as the star is covered in gas and dust due to its evolving state. The star also had a limited view through the Hubble telescope. Mauerhan mentioned that the star is set to take on a certain evolutionary path though it will not the team to a boring study. The future is likely to be more exciting as there might be many possibilities based on whether it blows up or mass transfer occurs, and it life after the mass transfer ends.[ Source ]
