For readers who were not doing astronomy three decades ago, the contrast between then and now is hard to appreciate. Before the appearance of the epochal papers of Leighton et al. and of Ulrich, no one knew that the sun oscillates in characteristic eigenfrequencies that can be observed on the surface of the sun. No one imagined that these waves can be used to make precise measurements of the characteristics of the interior of the nearest star. Today many thousands of solar eigenfrequencies are… Expand
Seismology of the Sun and Stars
Ground-based observations of the spectrum of solar oscillations have already permitted us to put tight constraints on the hydrostatic stratification of the sun, and to infer the angular velocityExpand
Do 5-minute oscillations of the Sun affect the magnetosphere and lithosphere of the Earth?
In this paper, we analyzed a number of problems that are relevant for the physics of solar-terrestrial relationships and the dynamics of geospheres. It is shown that permanent 5-minute oscillationsExpand
Sensitivity of Solar Oscillation Frequencies to Element Abundances
We are fortunate to live close enough to a pulsating star, the sun, for which we can resolve the disk and thereby measure the frequencies of thousands of its global modes of oscillation. TheseExpand
Introduction to Helio- and Astro- Seismology
During the 1970’s, the subject of helioseismology developed rapidly as generally satisfactory theoretical explanations for the by-then frequently-observed solar 5-minute oscillation appeared in theExpand
Solar Oscillations: Current Trends
Oscillations observed at the surface of the Sun through Doppler shifts of spectral lines or through irradiance measurements are used by solar physicists to investigate subsurface physical processes.Expand
Observational techniques to measure solar and stellar oscillations
As said by Sir A. Eddington in 1925: Our telescopes may probe farther and farther into the depths of space. At first sight it would seem that the deep interior of the sun and stars is less accessibleExpand
Ultra‐High‐Resolution Observations of MHD Waves in Photospheric Magnetic Structures
Here we review the recent progress made in the detection, examination, characterisation and interpretation of oscillations manifesting in small-scale magnetic elements in the solar photosphere. ThisExpand
The structure and dynamics of the sun from helioseismology, and the neutrino problem
The inversion of thousands of p-modes, identified with great accuracy, has clearly demonstrated the substantial correctness of the standard solar models. The use of the new equation of state andExpand
Waves in the Sun
In Chaps. 4 and 5, we discussed theoretical formulations for the waves and oscillations in homogeneous as well as nonhomogeneous media. In this chapter, we will show applications of the differentExpand
Five-Minute Solar Oscillations and Ion-Cyclotron Waves in the Solar Wind
We study the possible impact of the photospheric five-minute oscillations on the ion-cyclotron waves in the solar wind. We proceed from the assumption that the ion-cyclotron waves in the solar windExpand
