Modelling the Track of the GD-1 Stellar Stream Inside a Host with a Fermionic Dark Matter Core-Halo Distribution
Martín F. Mestre, Carlos R. Argüelles, Daniel D. Carpintero +2
Traditional studies on stellar streams typically involve phenomenological CDM halos or ad hoc dark matter (DM) profiles with different degrees of triaxiality, which preclude to…
On the correct computation of all Lyapunov exponents in Hamiltonian dynamical systems
Daniel D. Carpintero, J. C. Muzzio
The Lyapunov Characteristic Exponents are a useful indicator of chaos in astronomical dynamical systems. They are usually computed through a standard, very efficient and neat algor…
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…
Microvariability in AGNs: study of different statistical methods II. Light curves from simulated images
L. Zibecchi, I. Andruchow, S. A. Cellone +1
In a previous paper, we studied two statistical methods used to analyse the variability of active galactic nuclei (AGNs): the C and F statistics. Applying them to observed differen…
The Lyapunov exponents and the neighbourhood of periodic orbits
D. D. Carpintero, J. C. Muzzio
We show that the Lyapunov exponents of a periodic orbit can be easily obtained from the eigenvalues of the monodromy matrix. It turns out that the Lyapunov exponents of simply stab…
Effects of chaos on the detectability of stellar streams
Martín Mestre, Claudio Llinares, Daniel D. Carpintero
Observations show that stellar streams originating in satellite dwarf galaxies are frequent in the Universe. While such events are predicted by theory, it is not clear how many of…
