A star with mass less than the Sun (0.8 or less) that has been discovered in the milky way has puzzled scientists, who did not have that it could exist something like this, something that goes against current theories of star formation. The rarity of the star, called SDSS J102915 + 172927 is that it consists almost entirely of hydrogen and helium, with tiny amounts of some other element heavier than those two, i.e. what astronomers call metals. A generally accepted theory predicts that the stars as this one, with low mass and extremely low amounts of metals, should not exist because the clouds of matter from which stars are formed would never condense, explains Elisabetta Caffau, leading the team author of the finding, in a release from the European Southern Observatory (ESO), whose telescopes in Chile have discovered this rarity. Was a surprise finding, for the first time, a star in this prohibited area of theory and means that we may have that review models of star formation, adds this researcher from the University of Heidelberg, Germany, and the Paris Observatory.
