| Abstract: |
The energy release in solar flares may cause not only plasma eruptions in the corona and heliosphere, but also may lead to excitation of acoustic wave packets propagating inside the Sun. These waves are observed on the solar surface as ripples propagating from the places where high-energy particles hit the lower chromosphere. Observations of such seismic event (called “sunquakes”) provide important information about properties of the high-energy particles accelerated during the energy release events, their interaction with the plasma of the low atmosphere, hydrodynamic and MHD processes in solar flares, and also open perspectives for developing new helioseismic diagnostics. In this paper, I review some recent observational results and discuss an observing program for Solar-B to study such events. |
