LP-VIcode: A program to compute a suite of variational chaos indicators
(Elsevier, 2014-04)
An important point in analyzing the dynamics of a given stellar or planetary system is the reliable identification of the chaotic or regular behavior of its orbits. We introduce here the program LP-VIcode, a fully operational ...
Periodic orbits in a three-dimensional galactic potential model via averaging theory
(The European Physical Journal Plus, 2021)
94 Ceti: a triple star with a planet and dust disc
(OXFORD UNIV PRESS, 2016)
94 Ceti is a triple star system with a circumprimary gas giant planet and far-infrared excess. Such excesses around main sequence stars are likely due to debris discs, and are considered as signposts of planetary systems ...
Dynamical stellar masses via high angular resolution techniques
(Universidad de Valparaíso, 2021)
Multiple stellar systems are abundant in our galaxy. Almost half of solar-like field stars have at least one companion. Multiple systems are the perfect playground to de- termine the stellar mass, which the one of the ...
The nature of UCDs: Internal dynamics from an expanded sample and homogeneous database
(2008)
We have obtained high-resolution spectra of 23 ultra-compact dwarf galaxies (UCDs) in the Fornax cluster with -10.4>M_V>-13.5 mag (10^6<M/M_*<10^8), using FLAMES/Giraffe at the VLT. This is the largest homogeneous data set ...
The impact of bound stellar orbits and general relativity on the temporal behavior of tidal disruption flares.
(The American Astronomical Society, 2013-09-20)
We have carried out general relativistic particle simulations of stars tidally disrupted by massive black holes. When a
star is disrupted in a bound orbit with moderate eccentricity instead of a parabolic orbit, the ...
Radiating, slowly rotating bodies in general relativity

Spatial structure of regular and chaotic orbits in a self-consistent triaxial stellar system
(Springer, 2005-03)
We created a triaxial stellar system through the cold dissipationless collapse of 100,000 particles whose evolution was followed with a multipolar code. Once an equilibrium system had been obtained, the multipolar expansion ...
