The use of a liquid crystal as an optical modulator for use with a resonant scattering spectrometer has been investigated. Preliminary data indicate that using...

Ten years of continuous measurements of the radial velocity of the Sun have been used to estimate the contribution of various solar surface phenomena to the...

Magnetohydrodynamic (MHD) simulations of the solar atmosphere are often performed under the assumption that the plasma is fully ionized. However, in the lower...

The low l solar acoustic spectrum has been measured with great accuracy for intermediate radial order modes, n = 11-34 (Jimenez et al., 1986; Grec et al., 1983...

Updated solar frequency splitting measurements suggest a slight decrease of the rotation rate below 0.25 Rsolar and, albeit preliminary, rule out a core...

Two data series of disk integrated solar irradiance, taken by the Variability of the solar IRradiance and Gravity Oscillations (VIRGO) experiment on board the...

Using GOLF/SOHO data a detailed analysis of the solar background spectrum has been performed at high and low phases of solar activity cycle. The analysis...

The question of whether or not solar g-modes can be detected and identified from ground observations is addressed. The limitation imposed by the Earth's...

Oscillations in sunspot umbrae exhibit remarkable differences between the photosphere and chromosphere. We evaluate two competing scenarios proposed for...
