Overview

Scientific Rationale

Why an international workshop on asteroseismology & star clusters?

Understanding how stars form, evolve and die is one of the main goals of modern astrophysics. Asteroseismology, the study of stellar internal oscillation, offers a unique window into the deep interiors of stars. Space missions such as Kepler, GAIA, TESS and high-resolution spectroscopic observations have revolutionized our understanding of stellar physics by detecting pressure and gravity modes.

Interpreting these observations using modelling allows us to probe internal stellar processes from core to the surface and infer basic parameters such as effective temperature, surface gravity, differential rotation, chemical composition, and mixing.

Chemically Peculiar (CP) Stars & Star Clusters

The chemically peculiar (CP) stars are a group of main-sequence B, A, and F-type stars having peculiar surface elemental abundances and abnormal spectral line strengths. CP stars serve as crucial testbeds for understanding the interactions between pulsation, rotation, binarity, and chemical peculiarities in intermediate-mass stars.

Concurrently, star clusters provide ideal laboratories for testing stellar evolution theory. Because members of a star cluster share a common age, distance, and chemical composition, their positions on the Hertzsprung–Russell (H-R) diagram place unique constraints on stellar models. Star clusters provide masses, luminosities, and ages that reduce degeneracies in stellar modelling; however, asteroseismology reveals the internal physics that governs the evolutionary path of cluster members.

Fostering Synergistic Research

Despite the transformative success of both cluster astronomy and asteroseismology of CP stars, the two fields have largely evolved in parallel. Their synergy represents a natural, imperative step in modern astrophysics. The main aim of this workshop is to foster synergistic research between asteroseismology and stellar cluster studies making full use of existing ground- and space-based observational facilities to define a joint strategy for future missions and datasets.

Core Themes Covered

The workshop program is structured around six interdisciplinary themes:

• Application of Machine Learning (ML) and Artificial Intelligence (AI) for the classification of the different type of the pulsators
• Pulsating mergers and binary evolution
• Pulsating CP stars in the clusters
• Asteroseismology of the CP stars
• Importance of High-resolution spectroscopy for the Asteroseismology of the CP stars
• Space missions: overview and outlook
