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,…

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…
