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…
The distribution of open clusters in the Galaxy
H. Monteiro, D. A. Barros, W. S. Dias +1
In this work we explore the new catalog of galactic open clusters that became available recently, containing 1750 clusters that have been re-analysed using the Gaia DR2 catalog to…
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 spiral pattern rotation speed of the Galaxy and the corotation radius with GAIA DR2
Wilton S. Dias, Hektor Monteiro, Jacques R. D. Lépine +1
In this work we revisit the issue of the rotation speed of the spiral arms and the location of the corotation radius of our Galaxy. This research was performed using homogeneous da…
