Theoretical periods of normal modes of vibration of the Sun are compared with the observed periods of oscillation of the solar surface. It is inferred from the comparison that it may soon be possible to use solar oscillations to measure aspects of the internal structure of the Sun. 
Nonradial oscillations of solar models with an initial discontinuity in hydrogen abundance
Solar models are calculated with low central hydrogen abundance. The stability of these models is investigated. The eigenspectrum is computed and compared with the SCLERA observations of solarExpand
An Introduction to Helioseismology
In no other case has stellar variability been honed to such a sharp astrophysical tool as for the Sun. The extreme richness of oscillation data available for the Sun, as a result of its proximity andExpand
Computation of periods of acoustical oscillations of the Sun
DISCOVERY of the regular pulsations of the Sun was reported in 1975–1976 by three groups of investigators1–3. It has been difficult to identify these oscillations, particularly the very stable 2 h 40Expand
How deep is the solar convection zone
The interpretation by Hill and Caudell (1979) of some of their solar oscillation data as being due to g modes of degree greater than 20 seems to imply that the solar convection zone is much shallowerExpand
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
On Umbral Oscillations as a Sunspot Diagnostic
The observation that p-modes are attenuated in sunspots1, i.e. sunspots act as ‘sinks’ of acoustic wave energy, is explained by the transfer of energy to motions along the magnetic field lines. TheExpand
On the excitation of oscillations of the Sun (numerical models)
Numerical solutions of the general time-dependent gas-dynamical equations in linear adiabatic approximation are given for initial conditions imitating: (a) a central perturbation, (b) a boundaryExpand
Excitation of the Solar Oscillations by Objects Consisting of γ-Matter
Modern development of particle physics makes it probable that new, still undiscovered, particles exist interacting with the ordinary matter by means of gravitation onlu. Okun suggested to call suchExpand
Solar Interior Rotation and its Variation
This article surveys the development of observational understanding of the interior rotation of the Sun and its temporal variation over approximately forty years, starting with the 1960s attempts toExpand
160-min pulsation of the Sun: New observational results
The 1974–1988 Crimean measurements of the solar line-of-sight velocity continue to show the presence of a statistically significant periodicity P1 = 160.009 (±) min with an average harmonic amplitudeExpand

Observations of solar pulsations
We have modified our solar magnetograph to measure velocities at the solar surface, rather than magnetic fields. Using this apparatus, we have observed fluctuations of period 2 h 40 min, which areExpand
Possible long-period oscillations in solar radio emission at microwaves
Long-enduring bursts in the Sun at microwaves can occur in a succession, and rare examples of 41-min periodic structure are shown. The experimental difficulties for identifying such phenomena areExpand
Observation of free oscillations of the Sun
The Fraunhofer absorption lines for potassium and sodium on the Sun are compared with the corresponding lines in the laboratory using a resonant optical scattering method. The observed shifts betweenExpand
The five-minute oscillations as nonradial pulsations of the entire sun.
Calculations of the stability coefficient show that the Sun should be pulsating as a unit in nonradial modes of high order. The pulsations are driven by the superadiabatic gradient of the lowExpand

Special experiments have been performed to investigate the fluctuations of the intensity difference of the solar radio emission at two close frequencies. The autocorrelation functions and theirExpand
Contribution to the observation of the photospheric oscillations
Observations of the 300 s photospheric oscillation on large solar surfaces (up to 5′20″ in diameter) using a sodium optical resonance cell seem to show that the power at long horizontal wavelengthsExpand
A Mixed-up Sun and Solar Neutrinos
FOWLER1 has suggested that the negative result of the Davis et al.2 effort to detect neutrinos from the Sun might be due to the Sun being in a transient phase after having been mixed some millions ofExpand
The Solar Spoon
Overstability causes the Sun's core to mix every few hundred million years. This induces geological ice ages and temporarily depresses the solar neutrino flux.
Waves in the Solar Atmosphere
The study of waves in the solar atmosphere started with an attempt to explain the observed Doppler shifts (wiggly line spectra) and broadening of photospheric spectral lines. Then Biermann (1946) andExpand
The effect of primordial hydrogen/helium fractionation on the solar neutrino flux
If hydrogen and helium are immiscible below some critical temperature, gravitational separation could occur in the proto-sun, resulting in a nearly pure helium core and a nearly pure hydrogen shell.Expand
