Asteroseismology is a research area focused on probing the internal structure and dynamics of stars through the observation and modeling of their natural oscillation modes. By analyzing mode frequencies, splittings, amplitudes, and line profiles, it constrains stellar parameters such as internal rotation profiles, sound-speed distributions, convective zone depths, and core properties. The field relies on high-precision photometry and spectroscopy from space- and ground-based instruments, coupled with stellar pulsation theory and evolutionary models, to infer fundamental quantities including stellar ages, masses, and radii, thereby refining stellar evolution theory and improving characterization of exoplanet host stars.
Scientists have analyzed more than 40 years of astronomical data to uncover evidence that the sun's internal structure subtly changes from one solar cycle minimum to the next. Publishing their findings in Monthly Notices ...

Chinese astronomers have conducted an asteroseismology study of a newly discovered pulsating white dwarf designated WFST J053009.62+595557.0, or WFST J0530 for short. The new findings, presented January 2 on the arXiv pre-print ...
In the late 1980s, scientists realized they could understand the interior properties of the sun by observing the sound waves that resonate inside it. This technique, called helioseismology, revealed a mysteriously thin dynamical ...
