My Project
Solar magnetohydrodynamic (MHD) seismology studies oscillations and waves in the solar atmosphere, offering insights into the heating of the Sun's corona and solar wind acceleration. It explores physical mechanisms driving solar processes using observational data, theoretical models, and simulations. The field's applications extend to magnetospheric physics, stellar physics, and controlled fusion. Recent advances, fueled by high-resolution observations from the Solar Dynamics Observatory and Solar Orbiter, enable a more comprehensive study of MHD waves.
Slow magnetoacoustic waves, driven by oscillations in underlying solar layers, serve as a valuable seismological tool. They provide information on the coupling of layers of the solar atmosphere, magnetic field geometry, and the coronal heating function. Time-distance analysis, focusing on parameters like oscillation period and apparent speed, offers critical insights into the solar atmosphere. This project aims to enhance understanding of MHD waves in the solar corona, particularly slow magnetoacoustic waves, aiding in predicting and mitigating potential impacts on Earth.
