Objective
For almost two decades, we have been living in the golden age of asteroseismology. Yet, the major advances for solar-like stars have mostly concerned evolved red giants, leaving main-sequence stars comparatively unexplored. With current and upcoming space missions targeting less evolved stars, it is now crucial to deepen our understanding of the physical processes shaping stellar evolution. A key unresolved issue is angular momentum transport, where state-of-the-art models consistently fail to reproduce seismic observations. Filling the gap in internal constraints for main-sequence stars is essential to explain these discrepancies and build a coherent picture of stellar evolution across all phases.
A second fundamental challenge is stellar magnetism. While the Sun’s 11-year cycle has been thoroughly studied, the details mechanisms are not fully known. Understanding how dynamos operate across stellar mass, age, and composition is critical, not only for stellar physics but also because magnetic variability directly impacts exoplanet habitability.
Thanks to the wealth of high-quality photometric data from Kepler, TESS, and spectroscopic surveys, and with the imminent arrival of PLATO, MELODY is uniquely positioned to seize this opportunity. By combining asteroseismology, photometry, spectroscopy, and dynamo modeling, MELODY will be a game changer in our understanding of stellar spin and magnetism.
The breakthrough of MELODY is to trace, for the first time, the joint evolution of internal rotation, surface rotation, and magnetic activity in solar-like stars from the main sequence to the subgiant branch. This will provide unprecedented constraints on angular momentum transport to improve age determination and stellar dynamos, moving far beyond the solar paradigm.
By delivering the most complete characterization of thousands of stars, MELODY will transform stellar evolution theory and have broad impact on exoplanet science and Galactic archaeology.
