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.

Evolved massive stars at low-metallicity: III. A source catalog for the Large Magellanic Cloud

Ming Yang et al.

Summary: This study presents a clean, magnitude-limited multiwavelength source catalog for the Large Magellanic Cloud (LMC), with high data reliability and membership estimation accuracy. By comparing the color-magnitude diagrams and color distributions, it is found that the differences between LMC and Small Magellanic Cloud (SMC) are mainly attributed to metallicity and star formation history, leading to variations in stellar types and colors.

Testing Evolutionary Models with Red Supergiant and Wolf-Rayet Populations

Philip Massey et al.

Summary: Despite previous estimates showing a decrease in the relative number of red supergiants and Wolf-Rayet stars with increasing metallicity, this study found good agreement between new observations and the single-star Geneva and binary BPASS models.

Evolved massive stars at low-metallicity IV. Using the 1.6 μm H-bump to identify red supergiant stars: Case study of NGC6822?

Ming Yang et al.

Summary: This study identifies red supergiant (RSG) candidates in NGC6822 using a novel method, combining color-color diagrams and theoretical photometry to effectively separate different types of targets, with around 60% of the selected candidates being RSGs.

Grids of stellar models with rotation VI. Models from 0.8 to 120 M⊙ at a metallicity Z=0.006

Patrick Eggenberger et al.

Summary: The study presents a grid of single star models for masses between 0.8 and 120 M-circle dot, with and without rotation, representative of the Large Magellanic Cloud. The models show good agreement with observational data in terms of nitrogen surface enrichments and luminosity function of red supergiants. The results are important for comparisons with observations in the LMC and outer regions of the Milky Way, and numerical tables are provided for further studies.

A dusty veil shading Betelgeuse during its Great Dimming

M. Montarges et al.

Summary: Red supergiants are the most common final evolutionary stage of stars with initial masses between 8-35 times that of the Sun. During this stage, they experience substantial mass loss, which may affect their evolutionary path and ultimate fate. Observations of Betelgeuse's Great Dimming in 2020 suggest that mass loss from red supergiants may be inhomogeneous and linked to rapid changes in their photosphere brightness.

Red Supergiants in M31 and M33. I. The Complete Sample

Yi Ren et al.

Summary: The aim of this paper is to establish a complete sample of red supergiants in M31 and M33 using near-infrared colors and archival photometric data. The resulting sample of RSGs is considered complete, with a low pollution rate in the control fields. Additionally, the study identifies other types of stars and determines the tip-RGB with implications for the distance modulus to M31 and M33.

The Red Supergiant Content of M31 and M33

Philip Massey et al.

Summary: This study identifies red supergiants (RSGs) in M31 and M33 using near-IR photometry, deriving their physical properties and finding a higher extinction in M31 compared to M33. RSGs are mainly distributed along the spiral arms, while the older AGB population is more uniformly spread across the disk of each galaxy.
