Asteroseismology of the multiple stellar populations in the globular cluster M4

M. Tailo et al.

Summary: In this study, a new asteroseismic analysis based on K2 mission data was conducted on stars in the globular cluster M4, leading to the detection of solar-like oscillations in a large sample of 37 stars. By combining asteroseismology and multi-band photometry, estimates of mass and radius were obtained, in agreement with independent sources, reaffirming the reliability of asteroseismology in low metallicity regimes. The study also revealed important information about the mass differences between stellar populations in M4 and the presence of a mass-temperature gradient in red horizontal branch stars, providing valuable insights into the cluster's evolution.

TESS asteroseismology of the Kepler red giants

Dennis Stello et al.

Summary: Red giant asteroseismology can provide valuable information for studying the Galaxy. The TESS mission provides larger samples and the opportunity for full-sky asteroseismic inference. The results show clear oscillations in about 3000 stars and suggest the use of nu(max) as the seismic input to increase the number of stars.

Gaia Early Data Release 3: Photometric content and validation

M. Riello et al.

Summary: This paper focuses on the photometric content in Gaia Early Data Release 3 (Gaia EDR3), describing the input data, algorithms, processing, and validation of results. Significant improvements were made in the processing, particularly in the preprocessing and calibration of blue and red photometer data. The overall quality of calibrated mean photometry in Gaia EDR3 is superior to DR2 for all bands.

Bayesian calibration of the mixing length parameter alpha(ML) and of the helium-to-metal enrichment ratio Delta Y/Delta Z with open clusters: the Hyades test-bed

E. Tognelli et al.

Summary: The study tested the capability of a Bayesian procedure to calibrate helium abundance and the mixing length parameter, finding that the recovery of helium-to-metal enrichment ratio and mixing length parameter was more challenging, while accurate metallicity estimation provided stronger constraints on the models.

Star Formation Timescales of the Halo Populations from Asteroseismology and Chemical Abundances*

Tadafumi Matsuno et al.

Summary: The study found that the average mass of halo stars is 0.97 solar masses with an age of about 7 billion years, primarily contributed by Type Ia supernovae. There is a relative age dispersion of approximately 18% within the low-Mg population. The [alpha/Fe] and [Eu/Mg] ratios are different between the two subsamples, but there is no significant difference in the [s/Eu] ratio.

HAYDN High-precision AsteroseismologY of DeNse stellar fields

Andrea Miglio et al.

Summary: In the past decade, the Kepler and CoRoT missions have shown the potential of asteroseismology as a powerful tool for testing stellar physics and characterizing stellar properties. Advocating for a new space mission dedicated to collecting high-precision photometric data could lead to breakthroughs in stellar astrophysics.

Chronologically dating the early assembly of the Milky Way

Josefina Montalban et al.

Summary: Using asteroseismology, kinematics, and chemical abundances, precise stellar ages have been estimated for a sample of stars observed by the Kepler space mission. This sample includes some of the oldest stars formed inside the Galaxy as well as stars formed externally and subsequently accreted onto the Milky Way. This provides compelling evidence in favor of models suggesting the Galaxy already had a substantial population of stars before the infall of the satellite galaxy Gaia-Enceladus/Sausage around 10 billion years ago.

Age-dating Red Giant Stars Associated with Galactic Disk and Halo Substructures

Samuel K. Grunblatt et al.

Summary: Research suggests that most stars in the Milky Way stellar halo were likely accreted from a small number of relatively large dwarf galaxy merging events, although the timing of these events is still uncertain. By inferring robust stellar ages, it is possible to more directly determine the merger history of the Galaxy. Despite systematic differences in absolute and relative ages determined in this study, the age rankings of the stars in the sample are robust.
