Cratering and age of the small Saturnian satellites
(EDP Sciences, 2019-04-25)
Context. The small (=135 km mean radius) satellites of Saturn are closely related to its rings and together they constitute a complex dynamical system where formation and destruction mechanisms compete against each other. ...
Stellar occultations enable milliarcsecond astrometry for Trans-Neptunian objects and Centaurs
(2020-12-01)
Context. Trans-Neptunian objects (TNOs) and Centaurs are remnants of our planetary system formation, and their physical properties have invaluable information for evolutionary theories. Stellar occultation is a ground-based ...
A ring system detected around the Centaur (10199) Chariklo
(Nature Publishing Group, 2014-04)
Hitherto, rings have been found exclusively around the four giant planets in the Solar System. Rings are natural laboratories in which to study dynamical processes analogous to those that take place during the formation ...
The dynamical evolution of escaped Jupiter Trojan asteroids, link to other minor body populations
(Academic Press Inc Elsevier Science, 2019-02)
The Jupiter Trojans constitute an important asteroidal population both in number and also in relation to their dynamical and physical properties. They are asteroids located around L4 and L5 Lagrangian points on relatively ...
Surface composition? and dynamical evolution of two retrograde objects in the outer solar system: 2008 YB3 and 2005 VD
(EDP Sciences, 2013)
Most of the objects in the trans-Neptunian belt (TNb) and related populations move in prograde orbits with low eccentricity and
inclination. However, the list of icy minor bodies moving in orbits with an inclination above ...
Physical and dynamical characterization of (5201) Ferraz-Mello, a possible extinct Jupiter family comet
(EDP SCIENCES S A, 2008)
Context. The subject of asteroids in cometary orbits (ACOs) has been of growing interest lately. These objects have the orbital characteristics typical of comets, but are asteroidal in appearance, i.e., show no signs of a ...
Collisional and dynamical evolution of the L4 Trojan asteroids
(EDP Sciences, 2007-11)
Aims. In this paper, we analyze the collisional and dynamical evolution of the population of L4 Jovian Trojans. Methods. To do this, we test different collisional parameters and include a dynamical treatment, taking into ...
Análise biomecânica do andamento em potros da raça mangalarga marchador nos primeiros 15 dias de vida
(Universidade Estadual Paulista (Unesp), 2018-01-15)
Nosso estudo avaliou as características biomecânicas (comprimento e frequência da passada, deslocamento dorsoventral, potência dorsoventral, propulsão, potência médio lateral e potência total) de potros da raça Mangalarga ...
