[PPS15-P06] The Spatially-resolved HCN(J = 4-3) Interferometric Observation on Neptune's Stratosphere with ALMA Array
Keywords:ALMA array, Planetary atmosphere, Radio astronomy
ALMA array is a powerful tool to illustrate both the photochemistry and dynamics of gas giants' stratosphere thanks to its high spatial resolution and sensitivity. We have constructed the spatially-resolved HCN(J=4-3) map of Neptune with archived ALMA data obtained during Cycle-0 season. From the doppler-shift analysis, stratospheric dynamics of Neptune's stratosphere showing the spatial difference is illustrated clearly. In this presentation, obtained result and possible driving mechanism of the dynamics will be discussed.
