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...
We present an estimate of the solar rotation rate near the surface (i.e., the outer 1%) based on rotational splittings estimated for high degree modes ( ) from...
Solar site testing for the Advanced Technology Solar Telescope
The location of the Advanced Technology Solar Telescope (ATST) is a critical factor in the overall performance of the telescope. We have developed a set of...
Various aspects of the magnetism of the quiet sun are reviewed. The suggestion that a small scale dynamo acting at granular scales generates what we call the...
Solar-like oscillations in Kepler red giants (Hekker+, 2011)
For this investigation we use Kepler data obtained during the first four months of operation. These data have been analysed by different groups using already...
