A family of stacked central configurations in the planar fivebody problem
(201711)
Article
Open AccessWe study planar central configurations of the fivebody problem where three bodies, (Formula presented.) and (Formula presented.), are collinear and ordered from left to right, while the other two, (Formula presented.) and ... 
A note on a family of nongravitational central force potentials in dimension one
(Elsevier, 20171201)
Article
Open AccessIn this work, we study a oneparameter family of differential equations and the different scenarios that arise with the change of parameter. We remark that these are not bifurcations in the usual sense but a wider phenomenon ... 
A note on the dynamics around the L1,2 Lagrange points of the EarthMoon system in a complete solar system model
(2012)
Conference report
Open AccessThe purpose of this paper is the study of the phase space around the collinear libration points L1 and L2 of the Earth–Moon system when the gravitational effects of the remaining bodies of the Solar System are taken into ... 
A note on the dynamics around the Lagrange collinear points of the EarthMoon system in a complete Solar System model
(201302)
Article
Restricted access  publisher's policyIn this paper we study the dynamics of a massless particle around the L 1,2 libration points of the Earth–Moon system in a full Solar System gravitational model. The study is based on the analysis of the quasiperiodic ...

Conference report
Open AccessThis paper studies the dynamics of a massless particle around the libration points of the Earth  Moon system in a full Solar System gravitational model. The study is based on the analysis of the quasi  periodic ... 
An invitation to singular symplectic geometry
(2019)
Article
Open AccessIn this paper we analyze in detail a collection of motivating examples to consider bmsymplectic forms and foldedtype symplectic structures. In particular, we provide models in Celestial Mechanics for every bmsymplectic ... 
Analysis of the relative dynamics of a charged spacecraft moving under the influence of a magnetic field
(20180901)
Article
Open AccessWe analyse a dynamical scenario where a constantly charged spacecraft (follower) moves in the vicinity of another one (leader) that follows a circular Keplerian orbit around the Earth and generates a rotating magnetic ... 
Asymptotic density of collision orbits in the restricted circular planar 3 body problem
(20190312)
Article
Open AccessFor the Restricted Circular Planar 3 Body Problem, we show that there exists an open set U in phase space of fixed measure, where the set of initial points which lead to collision is O(µ120) dense as µ¿0 . 
Bifurcation of relative equilibria of the (1+3)body problem
(20150402)
Article
Open AccessWe study the relative equilibria of the limit case of the planar Newtonian 4body problem when three masses tend to zero, the socalled (1+3)body problem. Depending on the values of the infinitesimal masses the number of ... 
Capturing small asteroids into SunEarth Lagrangian points for mining purposes
(2012)
Conference report
Open AccessThe aim of this paper is to study the capture of small Near Earth Objects (NEOs) into the SunEarth L2 using lowthrust propulsion for mining or science purposes. As it is well known, the vicinity of these points is inside ... 
Central configurations of the planar coorbial satellite problem
(200410)
Article
Open AccessWe study the planar central configurations of the 1 +n body problem where one mass is large and the other n masses are infinitesimal and equal. We find analytically all these central configurations when 2=n=4. Numerically, ...
