On the first nu(6) anti-aligned librating asteroid family of Tina
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
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
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. ...
