Surveying exogenous species in Saturn with ALMA. II. Detecting and Mapping HCN

T. Fouchet, T. Cavalié, R. Moreno +3

Several external sources (the rings, the satellites, cometary impacts, interplanetary dust particles) supply material to the upper atmosphere of Saturn. The signature of this exter…

New 12C/13C and 14N/15N isotopic ratio measurements in Jupiter's stratosphere revealed by ALMA

C. Lefour, T. Cavalié, R. Moreno +4

The collision of comet SL9 with Jupiter in 1994 changed the chemical composition of the Jovian stratosphere for decades. New molecules were detected minutes after the impacts (HCN,…

Detection of stratospheric HCN and tropospheric CO in Uranus and the implication for their sources

T. Cavalié, R. Moreno, C. Lefour +16

Uranus belongs to the category of ice giants that are common in our Galaxy. However, Uranus is one of the least explored and understood planets in our Solar System. This work aims…

Observations of the temporal evolution of Saturn's stratosphere following the Great Storm of 2010-2011. II. Latitudinal distribution of CO and stratospheric winds

T. Cavalié, R. Moreno, C. Lefour +8

Saturn's Great Storm of 2010-2011 has produced two stratospheric hot spots, the "beacons," that eventually merged to produce a gigantic one in April and May 2011. This beacon pertu…

Surveying exogenous species in Saturn with ALMA I. Detecting and Mapping CO

Deborah Bardet, Thierry Fouchet, Thibault Cavalié +5

The origin of carbon monoxide (CO) in Saturn's stratosphere remains uncertain, with proposed sources including internal thermochemical production, cometary impacts, and exogenic ma…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Key Targets of Opportunity on Gas and Ice Giants and their satellites

Ricardo Hueso, Leigh N. Fletcher, Damya Souami +15

The Extremely Large Telescope (ELT) will transform our knowledge of the outer planets and their satellite systems; however the visibility of unique targets of opportunity with high…

The Polar Stratosphere of Jupiter

Vincent Hue, Thibault Cavalié, James A. Sinclair +13

Observations of the Jovian upper atmosphere at high latitudes in the UV, IR and mm/sub-mm all indicate that the chemical distributions and thermal structure are broadly influenced…

The Thermal Structure and Composition of Jupiter's Great Red Spot From JWST/MIRI

Jake Harkett, Leigh N. Fletcher, Oliver R. T. King +15

Jupiter's Great Red Spot (GRS) was mapped by the James Webb Space Telescope (JWST)/Mid-Infrared Instrument (4.9-27.9 micron) in July and August 2022. These observations took place…
