Ellipsoidal Modeling Framework for TNOs: the triaxial shape of (50000) Quaoar and its implications for Weywot and the dynamical environment
Giuliano Margoti, Felipe Braga Ribas, Eros Gradovski +4
The three-dimensional shapes of Trans-Neptunian Objects (TNOs) are notoriously difficult to determine due to their slow orbital motion and minimal variations in aspect angle over h…
Size, shape, density, and atmospheric limit of (50000) Quaoar revealed from 14 years of stellar occultation
Giuliano Margoti, Felipe Braga-Ribas, José Luis Ortiz +173
We present results from 28 stellar occultations by the large Trans-Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultat…
Central flashes during stellar occultations. Effects of diffraction, interferences, and stellar diameter
Bruno Sicardy, Luc Dettwiller
Central flashes occur during stellar occultations by solar system objects. We catalog diffraction effects on the flash with point-like stars, monochromatic waves and spherical tran…
Sunlight refraction in the mesosphere of Venus during the transit on June 8th, 2004
P. Tanga, Th. Widemann, B. Sicardy +6
Many observers in the past gave detailed descriptions of the telescopic aspect of Venus during its extremely rare transits across the Solar disk. In particular, at the ingress and…
Pluto's lower atmosphere structure and methane abundance from high-resolution spectroscopy and stellar occultations
E. Lellouch, B. Sicardy, C. de Bergh +3
Context: Pluto possesses a thin atmosphere, primarily composed of nitrogen, in which the detection of methane has been reported. Aims: The goal is to constrain essential but so far…
