摘要

Observations of an unprecedented quality made by ALMA on the Red Rectangle of CO(3–2)and CO(6–5)emissions are analysed jointly with the aim of obtaining as simple as possible a description of the gas morphology and kinematics.Evidence is found for polar conical outflows and for a broad equatorial torus in rotation and expansion.Simple models of both are proposed.Comparing CO(6–5)and CO(3–2)emissions provides evidence for a strong temperature enhancement over the polar outflows.Continuum emission(dust)is seen to be enhanced in the equatorial region.Observed asymmetries are briefly discussed.
