Hundreds or thousands of Near-Earth Asteroids (NEAs) are discovered every year, so being able to determine their orbits follow them successfully in the future is essential warn danger they could present. Numerous methods have been developed improve precision and efficiency calculations used Initial Orbit Determination (IOD), with Gauss’s method benchmark due its intuitive formulation, comparable precision, historical importance. Herein, we present results development a new open access tool...
Context. The physical characterization of trans-Neptunian objects is essential for improving our understanding the formation and evolution Solar System. Stellar occultation a ground-based technique that can be successfully used to determine some TNOs’ fundamental properties with high precision, such as size shape. Aims. This work aimed at constraining size, shape, geometric albedo dwarf planet candidate (307261) 2002 MS 4 through analysis nine stellar events. Using multichord detection, we...
This work aims at constraining the size, shape, and geometric albedo of dwarf planet candidate 2002 MS4 through analysis nine stellar occultation events. Using multichord detection, we also studied object's topography by analyzing obtained limb residuals between observed chords best-fitted ellipse. We predicted organized observational campaigns occultations 2019 2022, resulting in two single-chord events, four double-chord detections, three events with to up sixty-one positive chords. 13...
The Centaur (60558) Echeclus was discovered on March 03, 2000, orbiting between the orbits of Jupiter and Uranus. After exhibiting frequent outbursts, it also received a comet designation, 174P. If ejected material can be source debris to form additional structures, studying surroundings an active body like provide clues about formation scenarios rings, jets, or dusty shells around small bodies. Stellar occultation is handy technique for this kind investigation, as can, from Earth-based...
