Tracing Birth Properties of Stars with Abundance Clustering

Bridget L. Ratcliffe et al.

Summary: This study explores the link between the chemical abundances of stars and their origins in the Milky Way disk using cosmological simulations. The results show that groups of chemically similar stars have different birth places and ages. However, some formation paths lead to age dispersions that are inconsistent with observations. Overall, abundance clustering is a promising approach for studying the history of our Galaxy.

Mapping the Galactic Metallicity Gradient with Open Clusters: The State-of-the-Art and Future Challenges

Lorenzo Spina et al.

Summary: In this paper, the data collected for open cluster members were analyzed as a whole, and the resulting catalogue contains [Fe/H] and orbital parameters for 251 Galactic open clusters. The study found that the slope of the radial metallicity gradient traced by open clusters flattens beyond a certain distance, and the slope traced by open clusters in the [Fe/H]-Lz diagram also flattens beyond a certain velocity.

The chemical properties of the Milky Way's on-bar and off-bar regions: evidence for inhomogeneous star formation history in the bulge

Jianhui Lian et al.

Summary: Studies have shown that the on-bar and off-bar stars at larger radii in the Milky Way exhibit consistent chemical abundance distributions and relations, while noticeable differences exist at smaller radii. This suggests a common star formation history in the long bar and the disc, with possible explanations for the differences at smaller radii being a faster early quenching process or recent metal-poor gas accretion. Additionally, vertical variations in abundance distributions in the bar hint at vertical heating through the bar buckling process.

Gaia Early Data Release 3 Parallax bias versus magnitude, colour, and position

L. Lindegren et al.

Summary: The study found that the parallax bias in Gaia EDR3 data is dependent on factors such as magnitude, color, and ecliptic latitude of the source in a non-trivial way. While a definitive method for correcting the parallax is not yet possible, tentative expressions have been provided for researchers to use at their discretion.

Gaia Early Data Release 3 Summary of the contents and survey properties

A. G. A. Brown et al.

Summary: Gaia EDR3 is the early installment of the third data release from the Gaia project, providing astrometry and photometry for 1.8 billion sources brighter than magnitude 21, along with radial velocities from Gaia DR2. The data processing precision and homogeneity have significantly improved compared to the previous version, with additional information on celestial bodies and an updated celestial reference frame.

The Similarity of Abundance Ratio Trends and Nucleosynthetic Patterns in the Milky Way Disk and Bulge

Emily Griffith et al.

Summary: Comparing abundance ratio trends between Milky Way bulge and disk stars, it is found that they have nearly identical median trends, with some differences observed in high-Ia elements. This close agreement implies similar nucleosynthetic processes enriched both regions despite their different star formation histories and physical conditions.

Orbital Torus Imaging: Using Element Abundances to Map Orbits and Mass in the Milky Way

Adrian M. Price-Whelan et al.

Summary: The article introduces a new method for dynamical inference, Orbital Torus Imaging, which uses data on stellar kinematics and element abundances to infer the characteristics of orbits in the Milky Way galaxy. This method is shown to be more robust and requires fewer assumptions than traditional tools, demonstrating the potential of combining stellar labels with dynamical invariants.
