Molecular line emission maps of IRAS 18089. In all panels the ALMA line-integrated intensity (v_LSR ± 5 km s^-1) is shown in color and the gray contours are the ALMA 3 mm continuum with steps from 5, 10, 20, 40, 80, 160, and 320×σ_cont. The mm and MIR continuum peak positions are labeled and highlighted in red and pink. The red circle shows the aperture (1″ radius) used for spectra extraction toward the 3 mm continuum peak. A scale bar in the top left panel marks a spatial scale of 5 000 au. The ellipse in the bottom left and bottom right corner highlights the angular resolution of the line and continuum data.
