Asteroid modelling by starlight diffraction: The shape of Dimorphos, the satellite of (65803) Didymos
P. Tanga, K. Tsiganis, D. Souami +17
The DART spacecraft impacted Dimorphos, the satellite of (65803) Didymos, in September 2022. Evidence of crater formation and possible global reshaping has been obtained indirectly…
Observations of the temporal evolution of Saturn's stratosphere following the Great Storm of 2010-2011. II. Latitudinal distribution of CO and stratospheric winds
T. Cavalié, R. Moreno, C. Lefour +8
Saturn's Great Storm of 2010-2011 has produced two stratospheric hot spots, the "beacons," that eventually merged to produce a gigantic one in April and May 2011. This beacon pertu…
Constraining the size, shape, and albedo of the large Trans-Neptunian Object (28978) Ixion with multi-chord stellar occultations
Y. Kilic, F. Braga-Ribas, C. L. Pereira +81
Trans-Neptunian objects (TNOs) are among the most primitive remnants of the early Solar System, and constraining their sizes, shapes, albedos, and surface properties is essential f…
Coherent Differential Imaging of high-contrast extended sources with VLT/SPHERE
Axel Potier, Raphaël Galicher, Pierre Baudoz +6
High-contrast imaging relies on advanced coronagraphs and adaptive optics (AO) to attenuate the starlight. However, residual aberrations, especially non-common path aberrations bet…
Rings around irregular bodies I. Structure of the resonance mesh, applications to Chariklo, Haumea and Quaoar
Bruno Sicardy, Heikki Salo, Maryame El Moutamid +2
Three ring systems have been discovered to date around small irregular objects of the solar system (Chariklo, Haumea and Quaoar). For the three bodies, material is observed near th…
Modeling the formation of N2 and CH4 frost on Pluto's slopes
L. Lange, T. Bertrand, V. Belissa +3
Context. The equatorial region of Cthulhu as revealed by New Horizons appears to be generally dark and largely devoid of volatiles because its surface albedo is low. Localized brig…
