APOGEE-2 Discovery of a Large Population of Relatively High-Metallicity Globular Cluster Debris
José G. Fernández-Trincado, Timothy C. Beers, Anna. B. A. Queiroz +13
We report the discovery of a new, chemically distinct population of relatively high-metallicity ([Fe/H] ) red giant stars with super-solar [N/Fe] () identifi…
Effect of orbital trapping by bar resonances in the local U-V velocity field
Edmundo Moreno, José G. Fernández-Trincado, William J. Schuster +2
The effects in the local U-V velocity field due to orbital trapping by bar resonances have been studied computing fifteen resonant families in a non-axisymmetric Galactic potential…
APOGEE discovery of a chemically atypical star disrupted from NGC 6723 and captured by the Milky Way bulge
José G. Fernández-Trincado, Timothy C. Beers, Dante Minniti +26
The central (`bulge') region of the Milky Way is teeming with a significant fraction of mildly metal-deficient stars with atmospheres that are strongly enriched in cyanogen ($^{12}…
Dynamics of thick, open spirals in Perlas potentials
L. Chaves-Velasquez, P. A. Patsis, I. Puerari +2
The PERLAS potential has been successfully used in many studies related with the dynamics of the spiral arms \textit{on} the equatorial plane of normal (non-barred) spiral galaxies…
Boxy Orbital Structures in Rotating Bar Models
L. Chaves-Velasquez, P. A. Patsis, I. Puerari +2
We investigate regular and chaotic two-dimensional (2D) and three-dimensional (3D) orbits of stars in models of a galactic potential consisting in a disk, a halo and a bar, to find…
Detecting the growth of structures in Pure Stellar Disk Models
Diego Valencia-Enríquez, Ivânio Puerari, Leonardo Chaves-Velasquez
We performed a series of 3D N-body simulations where the initial conditions were chosen to get two sets of models; unbarred and barred ones. In this work, we analyze the growth of…
