In this work, we study the formation and chemical evolution of the Galactic bulge with particular focus on the abundance pattern ([Mg/Fe] versus [Fe/H]), metallicity, and age distribution functions. We consider detailed chemical evolution models for the Galactic bulge and inner disc, with the aim of shedding light on the connection between these components and the origin of bulge stars. In particular, we first present a model assuming a fast and intense star formation, with the majority of… Expand

Abundances of disk and bulge giants from high-resolution optical spectra
Context. Observations of the Galactic bulge suggest that the disk formed through secular evolution rather than gas dissipation and/or mergers, as previously believed. This would imply very similarExpand
Nitrogen evolution in the halo, thick disc, thin disc, and bulge of the Galaxy
We study the evolution of nitrogen (N) in the Galactic halo, thick disc, thin disc, and bulge by comparing detailed chemical evolution models with recent observations. The models used in this workExpand
Detailed Abundances in the Galactic Center: Evidence of a Metal-rich Alpha-enhanced Stellar Population
We present a detailed study of the composition of 20 M giants in the Galactic center with 15 of them confirmed to be in the Nuclear Star Cluster. As a control sample we have also observed 7 M giantsExpand
The inner two degrees of the Milky Way
Context. Although there have been numerous studies of chemical abundances in the Galactic bulge, the central two degrees have been relatively unexplored due to the heavy and variable interstellarExpand
Evolution of lithium in the Milky Way halo, discs, and bulge
In this work, we study the Galactic evolution of lithium by means of chemical evolution models in the light of the most recent spectroscopic data from Galactic stellar surveys. We consider detailedExpand
Formation of N-rich field stars in the high-density building blocks of the Galactic bulge

  • Monthly Notices of the Royal Astronomical Society
  • 2019
Recent observational studies of the Galactic bulge by APOGEE have revealed that about 1 per cent of the bulge stars have rather high nitrogen abundances ([N/Fe] > 0.5). We here numericallyExpand
Analysis of Integrated-Light Spectra of Galactic Globular Clusters
We present the results of determination of the age, helium mass fraction (Y) in terms of the used stellar evolutionary models, metallicity ([Fe/H]), and abundances of the elements C, O, Na, Mg, Ca,Expand
The Milky Way’s bulge star formation history as constrained from its bimodal chemical abundance distribution
We conduct a quantitative analysis of the star formation history (SFH) of the Milky Way's bulge by exploiting the constraining power of its stellar [Fe/H] and [Mg/Fe] distribution functions. UsingExpand
Heavy element evolution in the inner regions of the Milky Way
We present results for the evolution of the abundances of heavy elements (O, Mg, Al, Si, K, Ca, Cr, Mn, Ni and Fe) in the inner Galactic regions ($R_{GC} < 4$kpc). We adopt a detailed chemicalExpand
Modelling the chemical evolution of Zr, La, Ce, and Eu in the Galactic discs and bulge
We study the chemical evolution of Zr, La, Ce, and Eu in the Milky Way discs and bulge by means of chemical evolution models compared with spectroscopic data. We consider detailed chemical evolutionExpand


Chemical evolution of the Galactic bulge: different stellar populations and possible gradients
Context. The recent although controversial discovery of two main stellar populations in the Galactic bulge, one metal-poor with a spheroid kinematics and the other metal-rich with a bar-likeExpand
Formation and evolution of the Galactic bulge: constraints from stellar abundances
Aims. We compute the chemical evolution of the Galactic bulge in the context of an inside-out model for the formation of the Milky Way. The model contains updated stellar yields from massive stars.Expand
Two-component galactic bulge probed with renewed galactic chemical evolution model
Results of recent observations of the Galactic bulge demand that we discard a simple picture of its formation, suggesting the presence of two stellar populations represented by two peaks of stellarExpand
Evidence for a metal-poor population in the inner Galactic Bulge
The inner Galactic Bulge has, until recently, been avoided in chemical evolution studies due to extreme extinction and stellar crowding. Large, near-IR spectroscopic surveys, such as APOGEE, allowExpand
The metallicity distribution of bulge clump giants in Baade’s window
Aims. We seek to constrain the formation of the Galactic bulge by analysing the detailed chemical composition of a large sample of red clump stars in Baade’s window. These stars were selected toExpand
Galactic astroarchaeology: reconstructing the bulge history by means of the newest data
Context. The chemical abundances measured in stars of the Galactic bulge offer an unique opportunity to test galaxy formation models, as well as to impose strong constraints on the history of starExpand
Abundance Gradients and the Formation of the Milky Way
In this paper we adopt a chemical evolution model, which is an improved version of the Chiappini, Matteucci, & Gratton model, assuming two main accretion episodes for the formation of the Galaxy, theExpand
The chemical evolution of the Galaxy
The distribution of enriched material in the stars and gas of our Galaxy contains information pertaining to the chemical evolution of the Milky Way from its formation epoch to the present, providingExpand
Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. VI. Age and abundance structure of the stellar populations in the central sub-kpc of the Milky Way

Abstract The Galactic bulge is the least studied component of our Galaxy. Yet, its formation and evolution are key to understand the formation of the Galaxy itself. Studies on the Galactic bulge haveExpand
