Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
Circumpolar ocean stability on Mars 3 Gy ago
Schmidt F., Way M. J., Costard F. +3
What was the nature of the Late Hesperian climate? Warm and wet or cold and dry? Formulated this way the question leads to an apparent paradox since both options seem implausible.…
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…
Refined physical parameters for Chariklo's body and rings from stellar occultations observed between 2013 and 2020
B. E. Morgado, B. Sicardy, F. Braga-Ribas +78
The Centaur (10199) Chariklo has the first rings system discovered around a small object. It was first observed using stellar occultation in 2013. Stellar occultations allow the de…
Ancient and present surface evolution processes in the Ash regionof comet 67P/Churyumov-Gerasimenko
A. Bouquety, L. Jorda, O. Groussin +3
The Rosetta mission provided us with detailed data of the surface of the nucleus of comet 67P/Churyumov-Gerasimenko.In order to better understand the physical processes associated…
A Case Study of the May 30th, 2017 Italian Fireball
A. Carbognani, D. Barghini, D. Gardiol +25
On May 30th, 2017 at about 21h 09m 17s UTC a green bright fireball crossed the sky of north-eastern Italy. The fireball path was observed from some all-sky cameras starting from a…
Fine-scale observations of the Doppler frequency shifts affecting meteor head radio echoes
Jean-Louis Rault, Mirel Birlan, Cyril Blanpain +11
The French FRIPON (Fireball Recovery and Interplanetary Observation Network) programme relies on a video cameras network associated to radio sensors running in a radar multistatic…
Probing the use of spectroscopy to determine the meteoritic analogues of meteors
A. Drouard, P. Vernazza, S. Loehle +14
Determining the source regions of meteorites is one of the major goals of current research in planetary science. Whereas asteroid observations are currently unable to pinpoint the…
Martian zeolites as a source of atmospheric methane
Olivier Mousis, Jean-Marc Simon, Jean-Pierre Bellat +7
The origin of the martian methane is still poorly understood. A plausible explanation is that methane could have been produced either by hydrothermal alteration of basaltic crust o…
Instrumental Methods for Professional and Amateur Collaborations in Planetary Astronomy
O. Mousis, R. Hueso, J. -P. Beaulieu +57
Amateur contributions to professional publications have increased exponentially over the last decades in the field of Planetary Astronomy. Here we review the different domains of t…
