Latitudinal variations in Neptune's temperature profile observed with ALMA
Óscar 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…
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…
CHOH and HCN in Interstellar Comet 3I/ATLAS Mapped with the ALMA Atacama Compact Array: Distinct Outgassing Behaviors and a Remarkably High CHOH/HCN Production Rate Ratio
Nathan X. Roth, Martin A. Cordiner, Dominique Bockelée-Morvan +15
We report the detection of methanol (CHOH) toward interstellar comet 3I/ATLAS using the Atacama Compact Array of the Atacama Large Millimeter/Submillimeter Array (ALMA) on UT 2…
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…
Observations of Titan's Stratosphere During Northern Summer: Temperatures, CH3CN and CH3D Abundances
Alexander E. Thelen, Conor A. Nixon, Martin A. Cordiner +11
Titan's atmospheric composition and dynamical state have previously been studied over numerous epochs by both ground- and space-based facilities. However, stratospheric measurement…
Radiative-convective models of the atmospheres of Uranus and Neptune: heating sources and seasonal effects
G. Milcareck, S. Guerlet, F. Montmessin +10
The observations made during the Voyager 2 flyby have shown that the stratosphere of Uranus and Neptune are warmer than expected by previous models. In addition, no seasonal variab…
Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Planetary and Cometary Atmospheres
Martin A. Cordiner, Alexander E. Thelen, Thibault Cavalié +26
The study of planets and small bodies within our Solar System is fundamental for understanding the formation and evolution the Earth and other planets. Compositional and meteorolog…
A 3D picture of moist-convection inhibition in hydrogen-rich atmospheres: Implications for K2-18 b
Jérémy Leconte, Aymeric Spiga, Noé Clément +9
While small, Neptune-like planets are among the most abundant exoplanets, our understanding of their atmospheric structure and dynamics remains sparse. In particular, many unknowns…
An intense thermospheric jet on Titan
E. Lellouch, M. A. Gurwell, R. Moreno +7
Winds in Titan's lower and middle atmosphere have been determined by a variety of techniques, including direct measurements from the Huygens Probe over 0-150 km, Doppler shifts of…
The long-wavelength thermal emission of the Pluto-Charon system from Herschel observations. Evidence for emissivity effects
E. Lellouch, P. Santos-Sanz, S. Fornasier +9
Thermal observations of the Pluto-Charon system acquired by the Herschel Space Observatory in February 2012 are presented. They consist of photometric measurements with the PACS an…
Physical studies of Centaurs and Trans-Neptunian Objects with the Atacama Large Millimeter Array
A. Moullet, E. Lellouch, R. Moreno +1
Once completed, the Atacama Large Millimeter Array (ALMA) will be the most powerful (sub)millimeter interferometer in terms of sensitivity, spatial resolution and imaging. This pap…
