Determinação da forma de asteroides a partir da inversão de curvas de luz
(Universidade Estadual Paulista (Unesp), 2016-12-09)
The ligthcurves are obtanied through the monitoring of variation of the intensity of reflect luminosity by one object in fuction of the time. In the case of asteroid, the shape of the ligthcurves depending of its physical ...
Dynamical dispersal of primordial asteroid families
(2016-03-01)
Many asteroid families are identified and well characterized all over the main asteroid belt. Interestingly, however, none of them are older than 4. Gyr. Many mechanisms have been proposed to disperse such old primordial ...
Chaotic diffusion caused by close encounters with several massive asteroids The (4) Vesta case
(Edp Sciences S A, 2014)
Efeitos de torques gravitacionais na dinâmica de asteróides múltiplos

Nonextensive distributions of asteroid rotation periods and diameters
(Brasil, 2012)
We investigate the distribution of asteroid rotation periods from different regions of the solar system and diameter distributions of near-Earth asteroids (NEAs). We aim to verify if nonextensive statistics satisfactorily ...
On the Emmenthal distribution of highly inclined asteroids
(Wiley-Blackwell, 2011-12-01)
Highly inclined asteroids are objects with sin (i) > 0.3. Among highly inclined asteroids, we can distinguish between objects with inclinations smaller than that of the centre of the ?6= g - g6 secular resonance and objects ...

Analysis of physical phenomena associated with asteroid deect by kinetic impact
(2021-01-01)
We have as objective for the present work, to study the use of a kinetic impact technique as a way to deect asteroids that may present some risk of collision with the Earth at a certain moment, or even the interest in ...
Identification and dynamical properties of asteroid families
(2015-01-01)
Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large asteroids have been disrupted by impacts ...
Dynamics around an asteroid modeled as a mass tripole
(2020-01-01)
The orbital dynamics of a spacecraft orbiting around irregular small celestial bodies is a challenging problem. Difficulties to model the gravity field of these bodies arise from the poor knowledge of the exact shape as ...
