Solar oscillations and the effect of a comet impact
If such external influences as the impact of a comet on the solar surface could destroy or mask the coherence of observed solar oscillations, the scope and...
Solar oscillations from two widely separated stations
Potassium line data from observatories in Hawaii and Spain were used to establish the authenticity of complex solar oscillation signals. Combination of the two...
Mathematical formulas derived from solar p-mode frequencies not only accurately reproduce observed frequencies, but extrapolate them to limits beyond current...
A new approach to the study of the Sun's corona and its dynamical processes is possible with radar investigations in the frequency range of about 10-50 MHz. The...
Solar radius variations using LOI-T guiding pixels
The LOI (Luminosity Oscillations Imager) is a low resolution solar photometer built at the SSD of ESA. It is one of the instruments in the VIRGO experiment on...
Balloons, driven by hot air or some gas lighter than air, were the first artificial machines able to lift payloads (including humans) from the ground. After...
