Structure and evolution of a tidally heated star
Diana Estrella-Trujillo, S. Jane Arthur, Gloria Koenigsberger +1
The shearing motion of tidal flows that are excited in non-equilibrium binary stars transform kinetic energy into heat via a process referred to as tidal heating. In this paper we…
Orbits of globular clusters computed with dynamical friction in the Galactic anisotropic velocity dispersion field
Edmundo Moreno, José G. Fernández-Trincado, Angeles Pérez-Villegas +2
We present a preliminary analysis of the effect of dynamical friction on the orbits of part of the globular clusters in our Galaxy. Our study considers an anisotropic velocity disp…
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…
Induced differential rotation and mixing in asynchronous binary stars
Gloria Koenigsberger, Edmundo Moreno, Norbert Langer
Rotation contributes to internal mixing processes and observed variability in massive stars. A significant number of binary stars are not in strict synchronous rotation, including…
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…
CAPOS: the bulge Cluster APOgee Survey II. The Intriguing "Sequoia" Globular Cluster FSR 1758
María Romero-Colmenares, José G. Fernández-Trincado, Doug Geisler +15
We present results from a study of fifteen red giant members of the intermediate-metallicity globular cluster (GC) FSR 1758 using high-resolution near-infrared spectra collected wi…
