Advances in Space Research, 1999
Abstract The time-distance helioseismology (or helioseismic tomography) is a new promising method for probing 3-D structures and flows beneath the solar surface, which is potentially important for studying the birth of active regions in the sun's interior and for understanding the relation between the internal dynamics of active regions and ...

Laser heterodyne spectrometer for helioseismology
Applied Optics, 1986The technique of laser heterodyne spectroscopy has been applied to the measurement of solar oscillations. Coherent mixing of solar radiation with the output of a frequency-stabilized CO2 laser permits the measurement of fully resolved profiles of solar absorption lines with high spectral purity and excellent frequency stability. This technique has been

Perspectives in Helioseismology
Science, 1996Helioseismology is probing the interior structure and dynamics of the sun with ever-increasing precision, providing a well-calibrated laboratory in which physical processes can be studied under conditions that are unattainable on Earth. Nearly 10 million resonant modes of oscillation are observable in the solar atmosphere, and their frequencies need to

Solar Models and Helioseismology
2000Helioseismic results put very important constraints on structure of the solar models, which can not be reachable by another way. These constraints lead toward what we should do to obtain a solar model in good agreement with the Sun. In this connection, diffusion of chemical elements took its indispensable part in the standard solar models.
