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…
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…
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…
Exploring the origin of moving groups and diagonal ridges by simulations of stellar orbits and birthplaces
Douglas A. Barros, Angeles Pérez-Villegas, Jacques R. D. Lépine +2
The present paper is the culminating one of a series aimed to contribute to the understanding of the kinematic structures of the solar neighbourhood (SN), explaining the origin of…
The moving groups as the origin of the vertical phase space spiral
Tatiana A. Michtchenko, Douglas A. Barros, Angeles Pérez-Villegas +1
Using the Gaia data release 2 (DR2), we analyzed the distribution of stars in the close vicinity of the Sun in the full 3D position-velocity space. We have found no evidence of inc…
On the stellar velocity distribution in the solar neighborhood in the light of Gaia DR2
Tatiana A. Michtchenko, Jacques R. D. Lépine, Angeles Pérez-Villegas +2
The aim of this work is to contribute to the understanding of the stellar velocity distribution in the solar neighborhood (SN). We propose that the structures on the planes,…
