On the solution of Lambert's problem by regularization
(201812)
Article
Restricted access  publisher's policyLambert's problem is the twopoint boundaryvalue problem resulting from a twobody orbital transfer between two position vectors in a given time. It lies at the very heart of several fundamental astrodynamics and space ... 
Pseudoheteroclinic connections between bicircular restricted fourbody problems
(20161011)
Article
Open AccessIn this paper, we show a mechanism to explain transport from the outer to the inner Solar system. Such a mechanism is based on dynamical systems theory. More concretely, we consider a sequence of uncoupled bicircular ... 
Review of Lambert's problem
(2015)
Conference lecture
Open AccessLambert’s problem is the orbital boundaryvalue problem constrained by two points and elapsed time. It is one of the most extensively studied problems in celestial mechanics and astrodynamics, and, as such, it has always ... 
Spatial collinear restricted fourbody problem with repulsive Manev potential
(20170901)
Article
Open AccessWe outline some aspects of the dynamics of an infinitesimal mass under the Newtonian attraction of three point masses in a symmetric collinear relative equilibria configuration when a repulsive Manev potential (1/r+e/r2 ...

Stationkeeping of real EarthMoon libration point orbits using discretetime sliding mode control
(20141001)
Article
Restricted access  publisher's policyIn this work, stationkeeping of real Earth–Moon libration point orbits is studied using discretetime sliding mode control (DSMC). For comparison, a discrete linear quadratic regulator (DLQR) controller is also considered. ... 
Study of LEO to GEO transfers via the L1 SunEarth or EarthMoon libration points
(Universitat Politècnica de Catalunya, 200810)
Master thesis (preBologna period)
Open AccessA geosynchronous Transfer Orbit (GTO) is a type of transfer around the Earth between a low Earth orbit (LEO) and the geostationary orbit (GEO). After the launch to a LEO orbit, the orbit of spacecraft has the same inclination ... 
Study of the transfer between libration point orbits and lunar orbits in Earth–Moon system
(20170223)
Article
Open AccessThis paper is devoted to the study of the transfer problem from a libration point orbit of the Earth–Moon system to an orbit around the Moon. The transfer procedure analysed has two legs: the first one is an orbit of the ... 
Systematic study of the connections between the collinear libration points of a coherent SunEarthMoon restricted fourbody model
(2017)
Conference report
Restricted access  publisher's policyA new approach is proposed for the systematic detection and refinement of natural connections between the libration points eml1,2 of the EarthMoon system and sel1,2 of the SunEarth system. It makes use of the QuasiBicircular ... 
Systematic study of the dynamics about and between the libration points of the SunEarthMoon System

Tails and bridges in the parabolic restricted threebody problem
(20170101)
Article
Open AccessAfter a close encounter of two galaxies, bridges and tails can be seen between or around them. A bridge would be a spiral arm between a galaxy and its companion, whereas a tail would correspond to a long and curving set ... 
The motion of Saturn coorbital satellites in the restricted threebody problem
(2001)
Article
Open AccessThis paper provides a description of the motion of Saturn coorbital satellites Janus and Epimetheus by means of horseshoe periodic orbits in the framework of the planar restricted threebody problem for the mass parameter ... 
The scattering map in the spatial Hill's problem
(200611)
Article
Open AccessWe present a framework and methodology to compute the scattering map associated to heteroclinic trajectories in the spatial Hill's problem. The scattering map can be applied to design of zerocost transfer trajectories in ... 
Warp evidence in precessing galactic bar models
(EDP Sciences, 20160401)
Article
Open AccessMost galaxies have a warped shape when they are seen edgeon. The reason for this curious form is not completely known so far, so in this work we apply dynamical system tools to contribute to its explanation. Starting from ... 
Zero drift regions and control strategies to keep satellite in formation around triangular libration point in the restricted SunEarthMoon scenario
(20151001)
Article
Open AccessIn this work, we are interested in avoiding large variations in the mutual distances among multiple satellites and also in controlling their geometric configuration around an Earth Moon triangular point. Previous studies ... 
Zero, minimum and maximum relative radial acceleration for planar formation flight dynamics near triangular libration points in the EarthMoon system
(20141101)
Article
Restricted access  publisher's policyAssume a constellation of satellites is flying near a given nominal trajectory around L4 or L5 in the EarthMoon system in such a way that there is some freedom in the selection of the geometry of the constellation. We ...
