Smart: A program to automatically compute accelerations and variational equations
Daniel D. Carpintero, Nicolás P. Maffione, Facundo A. Gómez
Modern astronomical potentials modeling galaxies or stellar systems can be rather involved, and deriving their first derivatives (accelerations) and second derivatives (variational…
A tidally induced global corrugation pattern in an external disc galaxy similar to the Milky Way
Facundo A. Gómez, Sergio Torres-Flores, Catalina Mora-Urrejola +11
We study the two dimensional (2D) line-of-sight velocity () field of the low-inclination, late-type galaxy VV304a. The resulting 2D kinematic map reveals a global, coh…
Simulating cosmological substructure in the solar neighbourhood
Christine M. Simpson, Ignacio Gargiulo, Facundo A. Gómez +8
We explore the predictive power of cosmological, hydrodynamical simulations for stellar phase space substructure and velocity correlations with the Auriga simulations and Aurigaia…
On the relevance of chaos for halo stars in the solar neighbourhood II
Nicolas P. Maffione, Facundo A. Gómez, Pablo M. Cincotta +7
In a previous paper based on dark matter only simulations we show that, in the approximation of an analytic and static potential describing the strongly triaxial and cuspy shape of…
On the relevance of chaos for halo stars in the Solar Neighbourhood
Nicolás P. Maffione, Facundo A. Gómez, Pablo M. Cincotta +3
We show that diffusion due to chaotic mixing in the Neighbourhood of the Sun may not be as relevant as previously suggested in erasing phase space signatures of past Galactic accre…
The Relative Lyapunov Indicators: Theory and Application to Dynamical Astronomy
Zsolt Sándor, Nicolás Maffione
A recently introduced chaos detection method, the Relative Lyapunov Indicator (RLI) is investigated in the cases of symplectic mappings and continuous Hamiltonian systems. It is sh…
