Astrophysics: A direct view of Star/Disk Interactions

Artist’s impression of the streams of hot gas that build up stars. Matter from the surrounding protoplanetary disk, the birthplace of planets, is channeled onto the stellar surface by magnetic fields shocking the surface at supersonic velocity (Copyright: Mark A. Garlick).

A team including researchers from the Institute for Astrophysics of the University of Cologne has for the first time directly observed the columns of matter that build up newborn stars. This was observed in the young star TW Hydrae system located approximately 163 light years from Earth. This result was obtained with the Very Large Telescope Interferometer (VLTI) and its GRAVITY instrument of the European Southern Observatory (ESO) in Chile...
