Investigating a triple star system in formation

Astronomers have carried out the most accurate study so far of the cocoon of gas and dust surrounding the GG Tau A system. By combining complementary observations at submillimeter (ALMA and IRAM) wavelengths with those at infrared (VLTI/ESO) wavelengths, the researchers were able to identify the complex dynamics at work in GG Tau. For the first time, they detected motion of matter showing that exoplanets can form not only around one of the members of this trio of young stars, but also much further out in the disc surrounding the three stars.
