dc.description.abstractEn	Located at 140 pc, the environment of the young hierarchical TTauri star system GG Tau A remains a unique laboratory to study tidal interactions and planet formation. We report new ALMA observations of the triple star GG Tau A performed at 0.5mm and in CO J=6-5 at resolution of 0.3 arcsecond. These new images resolve out the massive and narrow dust ring and reveal that a large amount of CO gas is streaming inside the cavity or the gravitationally unstable area. The dust and gas disk surrounding GG Tau Aa which is separated by 35 AU from the binary GG Tau Ab, would not survive without regular replenishment form these streamers.
