Oscillatory motions in restricted N-body problems
We consider the planar restricted N-body problem where the N−1 primaries are assumed to be in a central configuration whereas the infinitesimal particle escapes to infinity in a parabolic orbit. We prove the existence of ... -
Periodic solutions, KAM tori and bifurcations in a cosmology-inspired potential
A family of perturbed Hamiltonians H = 1/2 (x^2 + X^2) − 1/2 (y^2 + Y^2)+1/2 (z^2 + Z^2) + 2[ (x^4 + y^4 + z^4) + (x^2 y^2 + x^2 z^2 + y^2 z^2)] in 1: −1:1 resonance depending on two real parameters is considered. We ... -
Reeb’s theorem and periodic orbits for a rotating Hénon–Heiles potential
We apply Reeb’s theorem to prove the existence of periodic orbits in the rotating Hénon– Heiles system. To this end, a sort of detuned normal form is calculated that yields a reduced system with at most four non degenerate ... -
Remarkable bolides recorded along August 2021 in the framework of the Southwestern Europe Meteor Network
The most remarkable fireballs observed along August 2021 in the framework of the Southwestern Europe Meteor Network (SWEMN) and the SMART project are presented in this work. These fireballs overflew the Iberian Peninsula ... -
Remarkable fireballs spotted in the framework of the Southwestern Europe Meteor Network along August and September 2022
Some of the bright bolides observed in the framework of the Southwestern Europe Meteor Network between August and September 2022 are described in this work. These have been spotted from the Iberian Peninsula. Their ... -
Singular reduction of resonant Hamiltonians
We investigate the dynamics of resonant Hamiltonians with n degrees of freedom to which we attach a small perturbation. Our study is based on the geometric interpretation of singular reduction theory. The flow of the ... -
The Southwestern Europe Meteor Network: development of new artificial intelligence tools and remarkable fireballs observed from January to February 2022
In this work we focus on the development of an artificial intelligence in the framework of the Southwestern Europe Meteor Network (SWEMN) and the SMART project. This is named AIMIE, and is capable of writing scientific ... -
The Southwestern Europe Meteor Network: new advances and analysis of bright fireballs recorded from September to December 2021
In this work we focus on some recent improvements performed in the framework of the Southwestern Europe Meteor Network (SWEMN) and the SMART project. Thus, by employing artificial intelligence methods, we have significantly ... -
The Southwestern Europe Meteor Network: notable meteors spotted between December 2022 and January 2023
We present in this report the analysis of some of the notable meteors registered in the framework of the Southwestern Europe Meteor Network between December 2022 and January 2023. These were recorded from Spain. Their peak ... -
The Southwestern Europe Meteor Network: recent advances and analysis of bright fireballs recorded along April 2021
We present here some recent improvements performed in the framework of the Southwestern Europe Meteor Network (SWEMN) and the SMART project. In particular, we focus on the development of the first digital database dedicated ... -
The Southwestern Europe Meteor Network: remarkable bolides recorded from March to May 2022
Some of the remarkable bolides spotted in the framework of the Southwestern Europe Meteor Network from March to May 2022 are described here. These have been observed from the Iberian Peninsula. Their absolute magnitude ... -
Stability and estimates near elliptic equilibrium points in hamiltonian systems and applications
En esta tesis se estudia la estabilidad no lineal de equilibrios elípticos de sistemas hamiltonianos autónomos con n grados de libertad. Se supone que la parte cuadrática es diagonalizable y que puede haber o no resonancias. ...
