Unveiling the physical and chemical conditions in the young disk around L1527

Abstract

Planets form in disks around young stars. The planet formation process may start when the protostar and disk are still deeply embedded within their infalling envelope. However, unlike more evolved protoplanetary disks, the physical and chemical structure of these young embedded disks are still poorly constrained. We have analyzed ALMA data for 13 CO, C 18 O and N2D + to constrain the temperature structure, one of the critical unknowns, in the disk around L1527. The spatial distribution of 13 CO and C 18 O, to…
