On the first nu(6) anti-aligned librating asteroid family of Tina
(Wiley-Blackwell, 2011-04-01)
Asteroid families are groups of bodies identified in the space of proper elements or of frequencies that share a common origin in the collisional break-up of their progenitors. Their dynamical evolution is shaped by the ...
Possible effects of secular resonances in Phobos and Triton
(Elsevier B.V., 2014)
Capture probability in the 3:1 mean motion resonance with Jupiter: an application to the Vesta family
(Dordrecht, 2014)
We study the capture and crossing probabilities in the 3:1 mean motion resonance
with Jupiter for a small asteroid that migrates from the inner to the middle Main Belt under
the action of the Yarkovsky effect. We use an ...
Sobre a dinâmica de rotação de um planeta através de um sistema médio
(Universidade Estadual Paulista (Unesp), 2013)
Let us consider a non-spherical body (usually a planet C1) which is in a keplerian orbit around C3 (Sun). We still consider a massive satellite (C2) around the target planet (C1). Our main task is to investigate the secular ...
Analysis of the secular problem for triple star systems
(Iop Publishing Ltd, 2013-01-01)
The long-term dynamics of the three-body problem is studied. the goal is to study the motion of a planet (m(1)) around a star (m(0)) that is perturbed by a third-body (m(2)) (a planet or a brown dwarf star). the gravitational ...
Secular effects of ultralight dark matter on binary pulsars
(American Physical Society, 2020-03)
Dark matter (DM) can consist of very light bosons behaving as a classical scalar field that experiences coherent oscillations. The presence of this DM field would perturb the dynamics of celestial bodies, either because ...
Ritmos e ciclos no clima local de Cuiabá/Várzea Grande - MT : uma análise secular (1912 a 2012)
(Universidade Federal de Mato GrossoBrasilInstituto de Ciências Humanas e Sociais (ICHS) – RondonópolisUFMT CUR - RondonopólisPrograma de Pós-Graduação em Geografia – Rondonópolis, 2015-11-13)
The main objective was to analyze trends and climatic oscillations in Cuiabá / Várzea
Grande. The specific objectives were: to analyze the climate pace in Cuiabá / Várzea Grande in
the period 1912-2012; study the ...
Young Stars at the Edge: Stellar Clustering in the Outer Regions of the M33 Disk
(2011)
We investigate the distribution of bright main sequence stars near the northern edge of the M33 disk. Clustering on sub-kpc scales is seen among stars with ages near 10 Myr, and two large star-forming complexes are identified. ...
