Wave chaos in rapidly rotating stars
F. Lignieres, B. Georgeot
TL;DR
This paper investigates how rapid rotation affects acoustic oscillations in stars, revealing a mix of regular and chaotic spectral patterns, which could enhance star seismology and demonstrate wave chaos in natural systems.
Contribution
It introduces a novel analysis of acoustic ray dynamics in rotating stars using quantum chaos concepts, highlighting the coexistence of regular and chaotic spectral features.
Findings
Eigenfrequency spectrum combines regular and irregular patterns.
Chaotic regions correspond to irregular spectral subsets.
Provides a new perspective for star seismology and wave chaos observation.
Abstract
Effects of rapid stellar rotation on acoustic oscillation modes are poorly understood. We study the dynamics of acoustic rays in rotating polytropic stars and show using quantum chaos concepts that the eigenfrequency spectrum is a superposition of regular frequency patterns and an irregular frequency subset respectively associated with near-integrable and chaotic phase space regions. This opens new perspectives for rapidly rotating star seismology and also provides a new and potentially observable manifestation of wave chaos in a large scale natural system.
