• Protostars acquire most of their masses from the surrounding gas disk in the first (10)^5 year from their birth. When the protostars are binary, their masses are supplied by accretion from the surrounding gas disk. We have reexamined the accretion with two dimensional numerical simulations. Binary protostars accrete gas mainly through two channels, outer one located near the less massive star (secondary) and inner one near the more massive star (primary). The inner channel is open only when the accreting gas has a small specific angular momentum. The gas accreting through the outer channel flows around the secondary and mainly goes to the primary. The primary accretes more than the secondary irrespectively of the angular momentum of the accreting gas.
