According to foreign media reports, there is a white dwarf star WD 1856 80 light years away from the earth. This dead star entered the final stage of life 6 billion years ago. This slow death is very lonely. In the process of death, some stars expand rapidly and become a giant “red giant” – swallowing any planet orbiting nearby like Betelgeuse. Eventually, they run out of fuel and collapse back into white dwarfs, which destroys everything behind them. This is not the case with < p > < p > WD 1856. For the first time, astronomers have discovered a giant planet about the size of Jupiter orbiting the Death Star WD 1856. They named it WD 1856b, a surprising discovery – it’s not only safe from destruction, but also proof that dead stars can still have planets suitable for life. < / P > < p > a new paper published in the journal Nature points out that whenever the Jupiter size planet transits in front of WD 1856, the light emitted by the star decreases by nearly half when viewed from earth. The process is extremely short because the planet orbits once every 1.4 days. It is reported that the white dwarf itself is only about 40% larger than the earth. As a result, the decline in brightness lasted only eight minutes, and the planet was 20 times as far away from its star as mercury was from the sun. < / P > < p > “the system is quite strange,” says astrophysicist Simon Campbell of Monash University in Australia. “In this case, the planet is seven times bigger than its host star!” < / P > < p > using data collected from ground-based telescopes, the team can also estimate the mass of the planet. Infrared data from the Spitzer Space Telescope suggest it could be 14 times the mass of Jupiter. < / P > < p > but if WD 1856 B is so close to its star, how does it survive the expansion phase? The team offers a possible explanation. < / P > < p > when its host star becomes a red giant, it may disturb the planets in the system and cause their orbits to skew. The disorderly dance of the universe may have helped to throw a planetary body like WD 1856b towards the star, which has been spinning around the star since then. Because it’s an aging white dwarf, it also gives the planet enough time to get close to it. This may mean that there are other planets spinning around the white dwarf. < / P > < p > the researchers pointed out that it is unlikely that the star could peel off some of its outer layers and survive the expansion phase. However, they concluded that the current theory of the process is likely to show that it was not formed in this way. The team said future observations should confirm whether WD 1856 B is really a planet or whether it is a failed star known as a “brown dwarf”. They pointed out that the coming James Webb telescope and Gemini Observatory will be the key to better understanding WD 1856b. In a press release, Ian crossfield said: “there is a search for potentially habitable transiting planets around white dwarfs. It’s going to be a pretty strange system, and you have to think about how planets survive for such a long time Global Tech
