According to research published on Wednesday, astronomers have detected a planet closely orbiting the smoldering remains of a dead star, the first time a dense exoplanet has been discovered.
It then collapses, reducing its burnt core.
It is white dwarf, shining an extremely dense stellar amber with the remaining thermal energy and slowly fading for billions of years.
Previous research has suggested that some white dwarfs may retain more distant remains of their planetary systems.
But so far, no planets orbiting the dead star were detected.
“A previous example of a similar system, where an object was seen passing in front of a white dwarf, showed only a debris field from a disintegrating asteroid.”
The planet is about ten times larger than its shrunken parent star, known as WD 1856 + 534.
Siu Xu, an assistant Astronomer In the US National Science Foundation’s Gemini Observatory, it is stated that because there was no trace of debris from around the planet, the researchers concluded It was intact.
In a statement from NSF’s NOIRLab, Xu said, “We have indirect evidence that planets exist around white dwarfs and ultimately finding such a planet is surprising.”
The statement states that the discovery suggests that the planets may end up in or around the habitable zone of the white dwarf, and potentially adapt to life even after their star has died, the statement said stated in.
However, it remains a mystery how the planet got so close to the white dwarf.
It is believed that the red giant phase does not make it likely that nearby planets will survive when the same process happens with our sun, Venus And Wed It can be expected that it will be connected to the Earth.
Vanderburg said, “Our finding suggests that WD 1856B is far from the original star, and then traveled inward after becoming a white dwarf in some way.”
“Now that we know that planets can survive the journey without being broken by the gravity of white dwarfs, we can look for other, smaller planets.”
After simulating various scenarios, the authors suggest that the WD 1586b may have been thrown into a close orbit due to interactions with other planets.
In an independent comment on the discovery, said Steven Parsons of the University of Sheffield, the discovery “offers a tantalizing possibility to explore additional planets in the system in the future”.
Current estimates that around a third of all Sun-like stars have an arrangement of planets, while Galaxy He said that these stars comprise about ten billion.
The white dwarf WD 1856 + 534 is just 82 light years from Earth, so Parsons said that the gravitational effects of other planets on the white dwarf could possibly be detected by space observatory missions.
He said, “This system has opened up a new field of exoplanetary research.”
