Dan Caselden was until the end of November 3, 2018, we are playing this video Fighting, when he wrote the history of the heavens. Each time she dies, she jumps to her laptop to investigate NASA’s astronomical observations.
Suddenly, early in the morning, something strange appeared. “It was very disruptive,” Caselden said. “It was moving faster than anything I could find. It was weak and fast, which made it very strange. ”
Caselden sent an email to the astronomers who were working with him as Background Creatures: Planet 9 work. After saying that it was probably a painting, he realized that he was looking for something unusual, something very weak 50 light years across the galaxy 200 miles per second. He was nicknamed WISE 1534-1043, but because of his unique appearance and accidental presence, he soon gave himself the nickname “Danger. ”
Astronomers now think that Caselden found a tiny purple-star tree that failed to contain the required amount of nuclear fusion inside it. “It’s like a star,” he said Sarah Casewell, an astronomer at the University of Leicester in the UK. “However, it doesn’t get enough of it to mix hydrogen in helium and start burning everything.”
The discovery of the Danger showed how much we have to learn about brown shorts. These objects are usually about 13 times larger than Jupiter to 75 or more, but where the two boundaries are an ongoing problem. “People argue against them in meetings all the time,” he said Beth Biller, an astronomer at the University of Edinburgh in the UK, especially at low altitudes. Even the 13 masses of Jupiter are about the same mass deuterium mixing can occur-Textures that distinguish small purple and large gas planets – boundaries can vary. “There is nothing special about Jupiter 13,” Biller said. “It’s totally difficult.”
Dark browns are also very hot. Extremely hot temperatures have a global average temperature of about 2,000 degrees Fahrenheit[2000 ° C]- “almost a candlelight,” says Biller. The temperature is below minus 200 degrees Fahrenheit[200 ° C]. Lacking their own heat source, tiny little children slowly chill through the air for billions of years. (Microbes, which interfere with the distance between the planets and the tiny purple ones, can remain cold. WANZERU 0855-0714 it’s down in the cold. “It’s the coolest thing we know outside of our sun,” Biller said.)
What a baby in purple may look like is almost unknown. Even though he has a name—provided by astronomer Jill Tarter in 1975 — probably no brown. They are very orange or red. “Whether it’s bad or bad it’s just a name,” he said Davy Kirkpatrick, an astronomer at the California Institute of Technology.
They also have air, and the atmosphere can show some kind of banding and spotless storm, such as on Jupiter. Last year, Biller and his colleagues used the winds to try wind speed near purple about 34 light years. He begins to see objects in the sky as they come and appear as they rotate, and then compares this speed with the measure of the speed of its internal elements that come from its magnets. Comparing the two conditions, the researchers calculated wind speeds of more than 2,300 miles[2,300 km]an hour – five times the wind speed of Jupiter.
Because the tiny purple dots differentiate between stars and planets, they can help us to understand both. Ultimately, to a large extent, the boundaries between the largest purple stars and the smallest stars can give us some idea of how nuclear fusion begins. The object must reach the temperature of around 3 million degrees Celsius at the core of nuclear disarmament, he said Nolan Grief of the University of Geneva in Switzerland; this ignites a chain that converts hydrogen into helium. But no one knows exactly how much mass is needed for this to happen, and by which time the purple baby becomes a star. “There’s a lot of stuff in the transformation of things that we don’t know about,” Biller said. “Where that boundary is exactly is one of the questions.”
