Gaia Data Release 3 Summary of the content and survey properties

A. Vallenari et al.

Summary: The third data release of the Gaia mission includes a wide range of new data products, such as an expanded radial velocity survey and extensive astrophysical characterisation. This release provides unprecedented quantity, quality, and variety of source astrophysical data, including spectrophotometry, radial velocities, variables, and astrophysical parameters. It will greatly enhance the potential of Gaia's astrometric, photometric, and radial velocity surveys.

ATOMIUM: ALMA tracing the origins of molecules in dust forming oxygen rich M-type stars Motivation, sample, calibration, and initial results

C. A. Gottlieb et al.

Summary: This paper presents the overview of the atomium program, which aims to study the gas phase and dust formation chemistry in the winds of evolved AGB and RSG stars using ALMA. The data analysis reveals the complexities in the wind kinematics of the studied sources and suggests that binary interactions may explain the non-monotonic behavior of the velocity field.

Bottom-up dust nucleation theory in oxygen-rich evolved stars

David Gobrecht et al.

Summary: The formation of alumina dust grains in oxygen-rich evolved stars is not well understood, but they play a key role in triggering stellar dust formation and mass loss. A detailed chemical-kinetic network describes the formation and destruction of aluminum-bearing molecules and dust-forming clusters in two model stars, revealing higher aluminum oxide abundances in Mira-like models compared to semi-regular variables. Global optimization techniques identify low-energy isomers for aluminum oxide clusters, with a homogeneous nucleation scenario showing energetic viability towards the bulk limit.

Stellar and substellar companions from Gaia EDR3 Proper-motion anomaly and resolved common proper-motion pairs

Pierre Kervella et al.

Summary: The multiplicity survey is significantly improved by using a combination of the PMa, CPM, and RUWE indicators, which enhances the exhaustivity of companion detection and improves accuracy. The detection of CPM companions for bright stars provides a useful proxy for estimating their distance with higher accuracy than the HIPPARCOS method.

The Great Dimming of Betelgeuse: A Surface Mass Ejection and Its Consequences

Andrea K. Dupree et al.

Summary: The bright supergiant Betelgeuse underwent a historic optical dimming event in 2020. Observations reveal a substantial mass ejection and resulting changes in temperature and density of the star. The ejected mass could represent a significant fraction of the star's total annual mass-loss rate.

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.

Analytic, dust-independent mass-loss rates for red supergiant winds initiated by turbulent pressure

Summary: By examining the role of vigorous atmospheric turbulence in initiating and determining the mass-loss rates of red supergiant stars, the study provides a first theoretical and fully analytic mass-loss rate prescription for these objects.

ATOMIUM: The astounding complexity of the near circumstellar environment of the M-type AGB star R Hydrae: I. Morpho-kinematical interpretation of CO and SiO emission

Ward Homan et al.

Summary: Evolved low- to intermediate-mass stars shed their gaseous envelope into complex circumstellar nebulae, with large-scale structures in the nebula likely originating from stellar wind and companion interactions. Observations of R Hydrae reveal a multi-layered structure with hollow bubbles, and evidence suggests the presence of a second nearby companion with estimated mass around 0.65 Solar masses.

ATOMIUM: halide molecules around the S-type AGB star W Aquilae

T. Danilovich et al.

Summary: S-type asymptotic giant branch (AGB) stars are intermediates in the evolution of oxygen- to carbon-rich AGB stars. The abundances of AlCl and AlF from rotational lines towards an S-type AGB star were determined for the first time. AlCl is found in clumps close to the star, while AlF emission is more extended. The AlF abundance exceeds solar levels, suggesting fluorine synthesis in the AGB star has reached the surface and circumstellar envelope.

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.

Summary: The observation and analysis of mass-loss processes in red supergiants revealed the presence of a dust-containing clump, indicating a possible connection to the overall mass lost from the star and potentially linked to localized surface activities.
