DISTRIBUTION OF TEMPERATURE IN THE DETAILS OF JUPITER'S DISK BASED ON THE ABSORPTION LINES OF THE NH 3 λ6450 Å BAND

In order to understand significant meteorological processes occurring in Jupiter’s atmosphere, studies were carried out on ammonia NH₃ absorption lines, whose relative amount is small but whose influence could be comparable to water vapor in Earth's atmosphere. These observations were performed using a high spectral resolution échelle spectrometer installed at the Cassegrain focus of the 2-meter telescope at Shamakhi Astrophysical Observatory. Variations in the intensity of NH₃ absorption lines in the NH₃ λ 6475Å band were studied in different regions of Jupiter’s disk and at the center of Saturn’s disk. In this spectral region, 20 lines were selected for the center, 14 lines for the northern zone, and 11 lines for the southern zone. The obtained data were processed using the DECH 95 and DECH 30 programs. The spectrophotometric characteristics of these spectral lines, including their equivalent widths and half-widths, were determined. Based on the observational data obtained, Jupiter’s rotational temperature was determined from different line pairs. The calculated temperatures vary between approximately 180 K and 80 K. The observed variations in temperature could be attributed to lightning events within these layers. Summarizing the obtained results, the average temperature in the details of Jupiter’s disk was determined to be approximately 127 K, aligning well with findings reported by other authors.
