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…

Fundamental parameters for 45 open clusters with Gaia DR2, an improved extinction correction and a metallicity gradient prior

H. Monteiro, W. S. Dias, A. Moitinho +5

Reliable fundamental parameters of open clusters such as distance, age and extinction are key to our understanding of Galactic structure and stellar evolution. In this work we use…

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…

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…
