Effects of Magnetic Fields on Solar Inertial Modes in Global Nonlinear Simulations
Conrado S. Finotti, Gustavo Guerrero, Santiago A. Triana +2
Solar inertial modes are increasingly viewed as probes of the solar interior, with recent helioseismic evidence indicating that these modes may be sensitive to the internal magneti…
Simulations of the onset and dynamical evolution of inertial waves in solar/stellar interior
Mariane D. Souza-Gomes, Conrado S. Finotti, Gustavo Guerrero +4
Inertial modes have been recently detected in the Sun via helioseismology, yet their origin, evolution, and role in the dynamics of the solar plasma and magnetic field remain poorl…
Transition to turbulence in the wide-gap spherical Couette system
Ankit Barik, Santiago A. Triana, Michael Hoff +1
The spherical Couette system consists of two differentially rotating concentric spheres with a fluid filled in between. We study a regime where the outer sphere is rotating rapidly…
Effects of the librationally induced flow in Mercury's fluid core with an outer stably stratified layer
Fleur Seuren, Santiago A. Triana, Jérémy Rekier +2
Observational constraints on Mercury's thermal evolution and magnetic field indicate that the top part of the fluid core is stably stratified. Here we compute how a stable layer af…
Electric interface condition for sliding and viscous contacts
Jérémy Rekier, Santiago A. Triana, Antony Trinh +1
First principles of electromagnetism impose that the tangential electric field must be continuous at the interface between two media. The definition of the electric field depends o…
Identification of inertial modes in the solar convection zone
Santiago Andrés Triana, Gustavo Guerrero, Ankit Barik +1
The observation of global acoustic waves (p modes) in the Sun has been key to unveiling its internal structure and dynamics. A different kind of wave, known as sectoral Rossby mode…
Inertial modes of a freely rotating ellipsoidal planet and their relation to nutations
Jeremy Rekier, Santiago A. Triana, Antony Trinh +1
We compute the inertial modes of a freely rotating two-layer planetary model with an ellipsoidal inviscid fluid core and a perfectly rigid mantle. We present a method to derive ana…
The coupling between inertial and rotational eigenmodes in planets with liquid cores
Santiago Andres Triana, Jeremy Rekier, Antony Trinh +1
The Earth is a rapidly rotating body. The centrifugal pull makes its shape resemble a flattened ellipsoid and Coriolis forces support waves in its fluid core, known as inertial wav…
Internal energy dissipation in Enceladus's ocean from tides and libration and the role of inertial waves
J. Rekier, A. Trinh, S. A. Triana +1
Enceladus is characterised by a south polar hot spot associated with a large outflow of heat, the source of which remains unclear. We compute the viscous dissipation resulting from…
Photometric detection of internal gravity waves in early-type stars observed by CoRoT
D. M. Bowman, C. Aerts, C. Johnston +8
Early-type stars are predicted to excite an entire spectrum of internal gravity waves (IGWs) at the interface of their convective cores and radiative envelopes. Numerical simulatio…
On the photometric detection of Internal Gravity Waves in upper main-sequence stars I. Methodology and application to CoRoT targets
D. M. Bowman, C. Aerts, C. Johnston +8
Context. Main sequence stars with a convective core are predicted to stochastically excite Internal Gravity Waves (IGWs), which effectively transport angular momentum throughout th…
A study of turbulence and interacting inertial modes in a differentially-rotating spherical shell experiment
Michael Hoff, Uwe Harlander, Santiago A. Triana
We present a study of inertial modes in a differentially rotating spherical shell (spherical Couette flow) experiment with a radius ratio of . Inertial modes are Coriolis-r…
Internal rotation of 13 low-mass low-luminosity red giants in the Kepler field
Santiago Andrés Triana, Enrico Corsaro, Joris De Ridder +3
The Kepler space telescope has provided time series of red giants of such unprecedented quality that a detailed asteroseismic analysis becomes possible. For a limited set of about…
Asteroseismology of 19 low-luminosity red giant stars from Kepler
F. Perez Hernandez, R. A. Garcia, E. Corsaro +2
Frequencies of acoustic and mixed modes in red giant stars are now determined with high precision thanks to the long continuous observations provided by the NASA Kepler mission. He…
Tight asteroseismic constraints on core overshooting and diffusive mixing in the slowly rotating pulsating B8.3V star KIC 10526294
Ehsan Moravveji, Conny Aerts, Peter I. Papics +2
KIC 10526294 is a very slowly rotating and slowly pulsating late B-type star. Its 19 consecutive dipole gravity modes constitute a series with almost constant period spacing. This…
Helioseismology in a bottle: modal acoustic velocimetry
Santiago Andrés Triana, Daniel S. Zimmerman, Henri-Claude Nataf +3
Measurement of the differential rotation of the Sun's interior is one of the great achievements of helioseismology, providing important constraints for stellar physics. The techniq…

Michel Rieutord, Santiago Andres Triana, Daniel S. Zimmerman +1
Spherical Couette flow (flow between concentric rotating spheres) is one of flows under consideration for the laboratory magnetic dynamos. Recent experiments have shown that such f…
Bi-stability in turbulent, rotating spherical Couette flow
