Normalization through invariants in n-dimensional Kepler problems
(Pleiades Publishing, 2018)
Artículo / Artikulua,
We present a procedure for the normalization of perturbed Keplerian problems in n dimensions based on Moser regularization of the Kepler problem and the invariants associated to the reduction process. The approach allows ...
Reeb’s theorem and periodic orbits for a rotating Hénon–Heiles potential
(Springer, 2019)
Artículo / Artikulua,
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 ...
Periodic solutions, KAM tori and bifurcations in a cosmology-inspired potential
(IOP Publishing, 2019)
Artículo / Artikulua,
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 ...
Analysis of bright bolides recorded between October and November 2022 by the Southwestern Europe Meteor Network
(MeteorNews, 2023)
Artículo / Artikulua,
We present in this work the analysis of some of the bright fireballs spotted in the framework of the Southwestern
Europe Meteor Network (SWEMN) between October and November 2022. They have been observed from the
Iberian ...
The Southwestern Europe Meteor Network: notable meteors spotted between December 2022 and January 2023
(MeteorNews, 2023)
Artículo / Artikulua,
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 ...
Remarkable bolides recorded along August 2021 in the framework of the Southwestern Europe Meteor Network
(MeteorNews, 2021)
Artículo / Artikulua,
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 ...

(MeteorNews, 2022)
Artículo / Artikulua,
Some of the bright bolides spotted in the framework of the Southwestern Europe Meteor Network from June to July
2022 are discussed here. These were observed from Spain. Their absolute magnitude ranges from –6 to –11. ...
Nonlinear stability in the spatial attitude motion of a satellite in a circular orbit
(Society for Industrial and Applied Mathematics Publications, 2021)
info:eu-repo/semantics/article,
The paper considers the attitude nonlinear stability analysis of the spatial satellite problem and takes it one step further. A study of the Lie (formal) stability is presented and long-time estimates related to the Lie ...
