Gas reaches young stars along magnetic field lines

Astronomers have used the GRAVITY instrument to study the immediate vicinity of a young star in more detail than ever before. Their observations confirm a thirty-year-old theory about the growth of young stars: the magnetic field produced by the star itself directs material from a surrounding accretion disk of gas and dust onto its surface. The results, published today in the journal Nature, help astronomers to better understand how stars like our Sun are formed and how Earth-like planets are pr...
