| Research Abstract |
A young binary is associated with three gas disks, which rotate around the primary, the secondary, and the common mass, respectively. We studied the gas flow from the circumbinary disk rotating around the common mass to the primary and secondary using numerical simulations of high resolution. We have confirmed that the gas flows mainly onto the primary and that the circumprimary and circumsecondary disks interact to form a bridge of dense gas. We have found that these features coincide with the near infrared image of a young binary, SR24, taken with the Subaru telescope.
