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 stringent upper limit of the PH abundance at the cloud top of Venus
T. Encrenaz, T. K. Greathouse, E. Marcq +7
Following the announcement of the detection of phosphine (PH) in the cloud deck of Venus at millimeter wavelengths, we have searched for other possible signatures of this molec…
Venus: Key to understanding the evolution of terrestrial planets
Colin Frank Wilson, Thomas Widemann
As we become aware of Earth's changing climate, and as we discover terrestrial planets in other solar systems, we gain ever more reasons to study the Earth's nearest neighbour and…
Atmospheric circulation of Venus measured with visible imaging-spectroscopy at the THEMIS observatory
Patrick Gaulme, Francois-Xavier Schmider, Thomas Widemann +3
Measuring Venus' atmospheric circulation at different altitudes is important for understanding its complex dynamics, in particular the mechanisms driving the super-rotation. Observ…
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…
Study of the plutino object (208996) 2003 AZ84 from stellar occultations: size, shape and topographic features
A. Dias-Oliveira, B. Sicardy, J. L. Ortiz +60
We present results derived from four stellar occultations by the plutino object (208996) 2003~AZ, detected at January 8, 2011 (single-chord event), February 3, 2012 (multi-c…
