Berlin, Oct 11 : New high-resolution observations with the VLT (Very Large Telescope) Interferometer of the European Southern Observatory in Chile reveal gas infall and outflow processes in the direct environment of six young stars.
An international team of astronomers, led by Stefan Kraus from the Max Planck Institute for Radio Astronomy in Bonn, Germany and Eric Tatulli from the Observatoire de Grenoble in France used the AMBER instrument to measure the geometry of atomic and molecular gas in the inner disk regions.
Surprisingly, they found that the gas emission can trace very distinct physical mechanisms.
These processes include infall of material onto the star as well as gas which is ejected from the system, likely in a disk wind.
