Maximum intensity (moment 8) map of the SiO J=5–4 line at 217.105 GHz (color scale and white contours) and continuum image (setup 1 at 225 GHz; magenta contours) in the innermost region of L483. The moment 8 image was produced using the velocity range of ±10 km s⁻¹ with respect to the systemic velocity of 5.5 km s⁻¹. The synthesized beam is shown in the bottom left corner of the image. Contour levels are 2, 4, and 8 times the rms noise level of 3.78 mJy beam⁻¹ for the maximum intensity and 4, 8, 16, and 32 times the rms noise level of 0.23 mJy beam⁻¹ for the continuum image, respectively. The 0.5^′′ × 0.5^′′ regions where spectra (Fig. 9) have been extracted (Table 2, Fig. A.1) are indicated by red squares. Small black plus signs show the positions of continuum peaks of the binary system (Cox et al. 2022). The axes of the blue and red lobes of the E–W outflow (Oya et al. 2018) with the PA of 105 degrees are plotted by solid blue and red lines, respectively.
