Abstract: Investigation of the triple stellar system GG Tau A reveals gas fragments within the central cavity between the Keplerian outer ring orbiting the entire system and the stars themselves; gas flow from this outer ring appears capable of sustaining the inner disk surrounding component star GG Tau Aa beyond the accretion lifetime, leaving time for planet formation to occur.
