The study of the Sun's interior by measuring oscillations (ripples) as they appear at the surface. The oscillations are caused by sound waves that originate at different depths inside the Sun. By measuring their travel times and the distance they travel, scientists can study conditions in the Sun's interior.
the study of wave oscillations on the Sun's surface.
Refers to the science of using waves to learn about the Sun. Helios is Greek for ‘sun' or ‘light'; seismos means ‘tremor'; and logos means ‘reasoning' or ‘discourse'. Just as seismologists learn about the interior of the Earth by listening and watching earthquakes, helioseismologists study waves from the Sun, although there are millions of times more waves to observe and listen to.
The branch of solar physics that studies how waves bounce around on the Sun. The behavior of these waves allows scientists to learn about the sun's interior.
The study of conditions far below the Sun's surface through the analysis of internal "sound" waves that repeatedly cross the solar interior.
The study of the surface of a star and how the surface is affected by the interior of the star.
The study of the interior of the Sun by the analysis of its natural modes of oscillation. more
A method for studing the Sun by utilizing waves that propagate throughout the star to measure its invisible internal structure and dynamics.
the study of the Sun's interior from observations of the Sun's pulsations on its surface.
Study of the the internal structure (i.e., density, temperature, abundance, etc.) and dynamics (i.e., mixing, rotation rate, etc.) of the sun from measurements of its surface oscillations.
Helioseismology is the study of the propagation of pressure waves in the Sun.Unlike seismic waves on earth, solar waves have practically no shear component (s-waves). Solar pressure waves are generated by the turbulence in the convection zone, near the surface of the sun, and certain frequencies are amplified by constructive interference. In other words, the turbulence "rings" the sun like a bell.
