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…
Latitudinal variations in Neptune's temperature profile observed with ALMA
Ãscar Carrión-González, Raphael Moreno, Emmanuel Lellouch +5
Despite the low solar irradiation it receives, Neptune shows a very active atmosphere with some of the most intense dynamics observed in Solar System atmospheres. Characterizing th…
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…
The Atmosphere of Titan in Late Northern Summer from JWST and Keck Observations
Conor A. Nixon, Bruno Bézard, Thomas Cornet +42
Saturn's moon Titan undergoes a long annual cycle of 29.45 Earth years. Titan's northern winter and spring were investigated in detail by the Cassini-Huygens spacecraft (2004-2017)…
Observations of the temporal evolution of Saturn's stratosphere following the Great Storm of 2010-2011 I. Temporal evolution of the water abundance in Saturn's hot vortex of 2011-2013
Camille Lefour, Thibault Cavalié, Helmut Feuchtgruber +6
Water vapour is delivered to Saturn's stratosphere by Enceladus' plumes and subsequent diffusion in the planet system. It is expected to condense into a haze in the middle stratosp…
