Frequency shifts of resonant modes of the Sun due to near-surface convective scattering
Jishnu Bhattacharya, Shravan. M. Hanasoge, H. M. Antia
Measurements of oscillation frequencies of the Sun and stars can provide important independent constraints on their internal structure and dynamics. Seismic models of these oscilla…
Simulating acoustic waves in spotted stars
Emanuele Papini, Aaron C. Birch, Laurent Gizon +1
Acoustic modes of oscillation are affected by stellar activity, however it is unclear how starspots contribute to these changes. Here we investigate the nonmagnetic effects of star…
Seismic Sounding of Convection in the Sun
Shravan Hanasoge, Laurent Gizon, Katepalli R. Sreenivasan
Our Sun, primarily composed of ionized hydrogen and helium, has a surface temperature of 5777~K and a radius km. In the outer , energy transpor…
