Radial modes of pressure bumps and dips in astrophysical discs
Armand Leclerc, Guillaume Laibe, Elliot Lynch +1
This study investigates the signatures of pressure extrema on global oscillations in discs. To this end, we use the framework of wave topology to establish a generalised local disp…
A core-sensitive mixed / mode of the Sun predicted by wave topology and hydrodynamical simulation
Arthur Le Saux, Armand Leclerc, Guillaume Laibe +2
Helioseismology has revolutionized our understanding of the Sun by analyzing its global oscillation modes. However, the solar core remains elusive, limiting a full understanding of…
The importance of Berry phase in solar acoustic modes
Armand Leclerc, Guillaume Laibe
An analytic expression for the frequencies of standing waves in stars, applicable to any radial order n, is derived from ray-tracing equations by the mean of Wigner-Weyl calculus.…
