Limit-cycle behavior in one-zone convective models
A. Munteanu, G. Bono, J. Jose +2
We present the results of a detailed set of one-zone models that account for the coupling between pulsation and convection following the original prescriptions of Stellingwerf (198…
The large-scale organization of chemical reaction networks in astrophysics
Ricard V. Sole, Andreea Munteanu
The large-scale organization of complex networks, both natural and artificial, has shown the existence of highly heterogeneous patterns of organization. Such patterns typically inv…
Creation of twistless circles in a model of stellar pulsations
Andreea Munteanu, Enrique Garcia-Berro, Jordi Jose +1
In the present paper, we study the Poincare map associated to a periodic perturbation, both in space and time, of a linear Hamiltonian system. The dynamical system embodies the ess…
A weakly non-adiabatic one-zone model of stellar pulsations: application to Mira stars
Andreea Munteanu, Enrique Garcia-Berro, Jordi Jose
There is growing observational evidence that the irregular changes in the light curves of certain variable stars might be due to deterministic chaos. Supporting these conclusions,…
