Outline of Research at the Start |
How does the magnetic field affect the formation of binary stars? This is a major outstanding question, given that half of Sun-like stars in the Milky Way Galaxy are in binary systems. Recent surveys by other telescopes have shown that very young star-forming sources fragment into binary systems on two different size scales as a result of two different formation mechanisms. Using cutting-edge data from the ALMA observatory, we will test these formation hypotheses in order to gain a better understanding of the origin of binary sources in our Galaxy.
