Propagating Linear Waves in Convectively Unstable Stellar Models: a Perturbative Approach
Emanuele Papini, Laurent Gizon, Aaron C. Birch
Linear time-domain simulations of acoustic oscillations are unstable in the stellar convection zone. To overcome this problem it is customary to compute the oscillations of a stabi…
Precise and accurate interpolated stellar oscillation frequencies on the main sequence
Warrick H. Ball, Jesper Schou, Laurent Gizon +1
High-quality data from space-based observatories present an opportunity to fit stellar models to observations of individually-identified oscillation frequencies, not just the large…
Seismic constraints on rotation of Sun-like star and mass of exoplanet
Laurent Gizon, Jérome Ballot, Eric Michel +32
Rotation is thought to drive cyclic magnetic activity in the Sun and Sun-like stars. Stellar dynamos, however, are poorly understood owing to the scarcity of observations of rotati…
Propagation of seismic waves through a spatio-temporally fluctuating medium: Homogenization
Shravan Hanasoge, Laurent Gizon, Guillaume Bal
Measurements of seismic wave travel times at the photosphere of the Sun have enabled inferences of its interior structure and dynamics. In interpreting these measurements, the simp…
Comparison of solar surface flows inferred from time--distance helioseismology and coherent structure tracking using HMI/SDO observations
M. Svanda, Th. Roudier, M. Rieutord +2
We compare measurements of horizontal flows on the surface of the Sun using helioseismic time--distance inversions and coherent structure tracking of solar granules. Tracking provi…
Helioseismology of sunspots: how sensitive are travel times to the Wilson depression and to the subsurface magnetic field?
Hannah Schunker, Laurent Gizon, Robert H. Cameron +1
In order to assess the ability of helioseismology to probe the subsurface structure and magnetic field of sunspots, we need to determine how helioseismic travel times depend on per…
