The long-term steady motion of Saturn's Hexagon and the stability of its enclosed jet-stream under seasonal changes
A. Sánchez-Lavega, T. del Río-Gaztelurrutia, R. Hueso +15
We investigate the long-term motion of Saturn's North-Pole Hexagon and the structure of its associated eastward jet, using Cassini ISS and ground-based images from 2008 to 2014. We…
Amateur Observers Witness the Return of Venus' Cloud Discontinuity
Kardasis E., Peralta J., Maravelias G. +13
Firstly identified in images from JAXA's orbiter Akatsuki, the cloud discontinuity of Venus is a planetary-scale phenomenon known to be recurrent since, at least, the 1980s. Interp…
Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations
J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…
A Long-lived Sharp Disruption on the Lower Clouds of Venus
J. Peralta, T. Navarro, C. W. Vun +19
Planetary-scale waves are thought to play a role in powering the yet-unexplained atmospheric superrotation of Venus. Puzzlingly, while Kelvin, Rossby and stationary waves manifest…
Morphology and dynamics of Venus's middle clouds with Akatsuki/IR1
J. Peralta, N. Iwagami, Sánchez-Lavega +8
The Venusian atmosphere is covered by clouds with super-rotating winds whose accelerating mechanism is still not well understood. The fastest winds, occurring at the cloud tops ($\…
Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016
E. Meza, B. Sicardy, M. Assafin +167
Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by th…
