Classical Cepheids in the Nuclear Stellar Disk: membership via dynamical analysis
M. De Leo, M. Zoccali, R. Albarracin +2
(abridged) Four classical Cepheids have been associated to the Nuclear Stellar Disk (NSD), suggesting a burst of star formation 20 Myrs ago. In this work, we analyse all available…
Chemical evolution of Na, Mg, and Al in the Galactic bulge from UVES data
R. P. Nunes, B. Barbuy, C. Chiappini +9
The formation of the Galactic bulge remains incompletely understood, with evidence pointing to different stellar populations, including a bar-driven component, an inner-disk popula…
On the use of field RR Lyrae as Galactic probes:. IX. Radial velocities
K. Baeza-Villagra, V. F. Braga, M. Fabrizio +25
We present the largest and most homogeneous catalog of radial velocity (RV) measurements for field RR Lyrae (RRL) variables, based on both proprietary and publicly available spectr…
Spectroscopic metallicities and first α-element abundances of RR Lyrae stars in Baade's Window
J. Olivares Carvajal, Á. Rojas-Arriagada, M. Zoccali +10
RR Lyrae stars in the bulge have been reported to be associated with the spheroidal, relatively metal-poor component. They offer a way to trace this component with precise distance…
Extinction law and stellar mass in the Nuclear Bulge from kinematically-selected red clump stars
Á. Valenzuela Navarro, M. Zoccali, E. Valenti +10
The Nuclear Bulge of the Milky Way harbors stellar populations that provide crucial insights into galaxy formation processes and serve as a nearby analog for understanding bulge fo…
Chemical radial gradients for the bulge-bar stellar populations from the APOGEE survey
J. V. Sales-Silva, K. Cunha, V. V. Smith +20
The Milky Way bulge-bar is composed of multiple populations. Using chemical and kinematical planes, we segregate six populations in a bulge-bar sample observed by the APOGEE survey…
Gaia FGK Benchmark Stars: Selecting Infrared Lines for Abundance Determination
Scarlet Elgueta, Paula Jofré, Claudia Aguilera-Gómez +7
The advent of new and more powerful infrared spectrographs has significantly motivated the advancement of the study of atomic and molecular line lists and stellar atmosphere models…
On the Use of Field RR Lyrae as Galactic Probes -- VIII. Early Formation of the Galactic Spheroid
G. Bono, V. F. Braga, M. Fabrizio +54
We introduce a new photometric catalog of RR Lyrae variables (RRLs, 300,000) mainly based on data available in public datasets. We also present the largest and most homogeneo…
