Dust and gas temperature maps. Top: dust temperature map obtained from Bonne et al. (2023) generated with the 160 µm/250µm flux density ratio as described in the work by Palmeirim et al. (2013). Bottom: gas kinetic temperature map combined temperature maps derived from the HCN/HNC and H¹³CN/HN¹³C emission line ratios. The black contours represent the 3.6 mm continuum emission. The bright green star indicates the position of the B2-type star D18-05. The beams for the T_dust and T_HCN/HNC maps are 18″ and 3.43 × 2.76 with a position angle of 13.66° displayed in the lower left corner.
