Brown dwarf star is coldest found
From Times Staff and Wire Reports
French and Canadian researchers have discovered the coldest brown dwarf star ever observed, a ball of gas about 15 to 30 times the size of Jupiter and with a temperature of about 660 degrees Fahrenheit.
Located about 40 light-years from Earth, the star, called CFBDS J005910.83-011401.3, is an isolated object, meaning it doesn’t orbit another star.
Two classes of brown dwarfs are known: those with temperatures from 2,200 degrees to 3,600 degrees and those with temperatures below 2,200 degrees. The newly observed object may be the prototype of a third class, the team reported Thursday in Astronomy & Astrophysics.
