What's Wrong With The Zombie Star?

TL;DR

Astronomers discovered a star, nicknamed the "zombie star," that exploded once in 1954 and then again in 2014, defying the usual lifespan of supernovas and leaving scientists puzzled.

Transcript

in September 2014 astronomers discovered IPT f-14 HL s now that's a weird name so let's go in its nickname which is a zombie star this zombie star is basically exploding a star a supernova which in best was a huge star with mass about 50 times the mass of our Sun now as far as we know about the supernova explosions when a supernova explosion occurs...

Key Insights

• 🤩 The "zombie star" is an unusual phenomena in astronomy, defying the typical behavior of supernovas.
• 🔅 Its prolonged brightness and intermittent fluctuations in brightness remain unexplained.
• 🤩 Analysis of past data revealed a supernova explosion in the same location in 1954, suggesting the star exploded twice.

Questions & Answers

Q: What is the zombie star?

The zombie star is a nickname given to a star that exploded like a supernova but did not fade away as expected. It remained bright for over 1,000 days, defying the typical behavior of supernovas.

Q: How is the zombie star different from other supernovas?

The zombie star stands out because it exploded twice—once in 1954 and again in 2014. Supernovas usually result in the star losing all its mass and not being able to explode again.

Q: Why did the zombie star's brightness fluctuate periodically?

Astronomers are unsure why the zombie star's brightness fluctuated during its prolonged lifespan. The intermittent changes in brightness remain a mystery and require further investigation.

Q: What could be the cause of the zombie star's extended brightness?

Some astronomers propose that the zombie star is the first recorded example of a pair-instability supernova, where the star's core becomes hot enough to create both matter and antimatter. This process would lead to a massive explosion at the star's center and a partial supernova.

Summary & Key Takeaways

• In 2014, astronomers found a star, known as the zombie star, that exploded like a supernova, but instead of fading away after 100 days, it continued to shine for over 1,000 days.

• Analysis of data revealed that the same location had experienced a supernova explosion in 1954, indicating that the star had exploded twice.

• The zombie star's prolonged brightness and intermittent fluctuations in brightness are still unexplained, leading astronomers to propose it as the first recorded instance of a particular type of supernova.
