You have got to feel for brown dwarfs. Not only has their failure to ignite like normal stars earned them an unfortunate nickname — failed stars — but new findings from the Hubble Space Telescope have revealed they can't even hold a relationship together., develop overly dense patches that collapse. Unlike your regular old star, however, a brown dwarf can't quite gather enough material from the remains of that cloud to pile on enough mass and kickstart thein its core.
In a way but this makes brown dwarfs a bit like the cosmic equivalent of the distracted boyfriend meme. You know the one. Hubble allows astronomers to detect binaries with components that sit as close as 298 million miles from one another. This is equivalent to around three times the. The researchers then narrowed this sample down until they obtained some of the coldest and lowest mass failed stars in the relative vicinity of the, which has a temperature of around minus 166 degrees Fahrenheit .
Scientists theorized that the lack of observed binary brown dwarfs suggested that they struggle to stay gravitationally bound over long periods of time. This new Hubble find adds further support to this concept.
