Generate synthetic observational predictions to guide future high-sensitivity and high-angular-resolution ALMA studies of early protoplanetary disc formation and kinematics.
Performed radiative transfer modelling of a massive (0.39 M⊙) self-gravitating disc embedded within a 10 M⊙ dense core configured similarly to the pre-stellar core L1544.
Simulated high-resolution ALMA interferometric line observations for multiple simple chemical species.
Identified C17O 3→2, HCO+ 3→2, OCS 26→25, and H2CO 404→303 transitions as effective spectral probes of disc structure.
Showed that these molecular emission lines reliably trace gas kinematics across both envelope and disc scales in young, self-gravitating systems.
