Comparing dynamical effects of the central bar and the spiral arms in the solar neighborhood
Willian Y. Nacafucasaco, Tatiana A. Michtchenko, Douglas Barros +1
The dynamical effects on the stellar motion produced by the Galactic central bar and the spiral arms perturbations are investigated separately and compared. The stars from the Gaia…
Chaotic diffusion in the action and frequency domains: estimate of instability times
Gabriel Teixeira Guimarães, Tatiana Alexandrovna Michtchenko
Purpose: Chaotic diffusion in the non-linear systems is commonly studied in the action framework. In this paper, we show that the study in the frequency domain provides good estima…
3D stellar motion in the axisymmetric Galactic potential and the e-z resonances
Tatiana A. Michtchenko, Douglas A. Barros
The full phase space information on the kinematics of a huge number of stars provided by the Gaia third Data Release raises the demand for a better understanding of the 3D stellar…
Past and present dynamics of the circumbinary moons in the Pluto-Charon system
Cristian A. Giuppone, Adrián Rodríguez, Tatiana A. Michtchenko +1
The Pluto-Charon (PC) pair is usually thought of as a binary in the dual synchronous state, which is the endpoint of its tidal evolution. The discovery of the small circumbinary mo…
Dynamics of the spiral-arm corotation and its observable footprints in the Solar Neighborhood
Douglas A. Barros, Angeles Pérez-Villegas, Tatiana A. Michtchenko +1
This article discusses the effects of the spiral-arm corotation on the stellar dynamics in the Solar Neighborhood (SN). All our results presented here rely on: 1) observational evi…
Eclipse timing variation of GK Vir: evidence of a possible Jupiter-like planet in a circumbinary orbit
Leonardo A. Almeida, Elielson S. Pereira, Gislene M. Borges +3
Eclipse timing variation analysis has become a powerful method to discover planets around binary systems. We applied this technique to investigate the eclipse times of GK Vir. This…
