Wave topology of stellar inertial oscillations
Armand Leclerc, Guillaume Laibe, Nicolas Perez
Inertial waves in convective regions of stars exhibit topological properties linked to a Chern number of 1. The first of these is a unique, unidirectional, prograde oscillation mod…
PT and anti-PT symmetries for astrophysical waves
Armand Leclerc, Guillaume Laibe, Nicolas Perez
Context: Discrete symmetries have found numerous applications in photonics and quantum mechanics, but remain little studied in fluid mechanics, particularly in astrophysics. Aims:…
Topology of shallow-water waves on the rotating sphere
Nicolas Perez, Armand Leclerc, Guillaume Laibe +1
Topological properties of the spectrum of shallow-water waves on a rotating spherical body are established. Particular attention is paid to its spectral flow, i.e. the modes whose…
