RR Lyrae stars (RRLs) are excellent tracers of stellar populations for old, metal-poor components in the the Milky Way and the Local Group. Their luminosities have a metallicity...

The Measuring at Intermediate Metallicity Neutron-Capture Elements (MINCE) project aims to provide high-quality neutron-capture abundances measurements for several hundred stars...

The correlations between star formation rate (SFR), stellar mass (M), and gas-phase metallicity (12+log(O/H)) for star-forming (SF) galaxies, known as global scaling relations...

The detailed age-chemical abundance relations of stars measure time-dependent chemical evolution. These trends offer strong empirical constraints on nucleosynthetic processes,...

The analysis of star cluster ages in tandem with the morphology of their H II regions can provide insight into the processes that clear a cluster's natal gas, as well as the...

Various element transport processes modify the photospheric chemical composition of low-mass stars during their evolution. The most prominent one is the first dredge-up that...

Ionized nebulae provide critical insights into the conditions of the interstellar medium (ISM). Their bright emission lines enable the measurement of physical properties, such...

We present an analysis of the chemical abundance properties of ~650 star-forming galaxies at z~=0.6-1.8. Using integral-field observations from the K-band multi-object...

Analysing stellar parameters and abundances from nearly one million Gaia DR3 Radial Velocity Spectrometer (RVS) spectra poses challenges due to the limited spectral coverage...

In this work, we studied the distribution of lithium abundances in giants as a function of stellar mass. We used a sample of 1240 giants common among Kepler photometric and...

We present a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric metallicity and distance estimates from our newly calibrated P-{Phi}31-R_21_-[Fe/H]/P-R_21_-[Fe/H]...

Evidence for similar chemical characteristics around low- and high-mass protostars has been found: in particular, a variety of carbon-chain species and complex organic molecules...

We report the first star formation history study of the Milky Ways nuclear star cluster (NSC), which includes observational constraints from a large sample of stellar...

We measure abundances of 12 elements (Na, Mg, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni) in a sample of 86 metal-poor (-2<~[Fe/H]<~-1) subgiant stars in the solar...

The dispersion in chemical abundances provides a very strong constraint on the processes that drive the chemical enrichment of galaxies. Due to its proximity, the spiral galaxy...

The recent detection of super-solar carbon-to-oxygen and nitrogen-to-oxygen abundance ratios in a bunch of metal-poor galaxies at high redshift by the James Webb Space Telescope...

Globular clusters (GCs) are extremely intriguing systems that help in reconstructing the assembly of the Milky Way via the characterisation of their chemo-chrono-dynamical...

The third Data Release of the ESA Gaia mission has provided a large sample of new gravity-mode pulsators, among which more than 11600 are {gamma} Dor stars. The goal of the...

Recent evidence from spectroscopic surveys points towards the presence of a metal-poor, young stellar population in the low-alpha, chemically thin disk. In this context, the...

We aim to constrain the chemo-dynamical properties of the Sagittarius (Sgr) dwarf galaxy using carbon abundances. At low metallicities in particular, these properties reveal the...
