Se han analizado series temporales de las fluctuaciones de la irradiancia solar integrada sobre el disco provenientes del experimento espacial "Variability of the solar IRradiance and Gravity Oscillations" (VIRGO) durante dos épocas correspondientes una, a un máximo de actividad magnética, y la otra, a un mínimo. En cada caso, se han ajustado las

The Σ beam asymmetry in the photoproduction of neutral pions from quasi-free nucleons in a deuteron target was measured for the first time between 0.60 and 1.50GeV, with the GRAAL polarized and tagged photon beam. The asymmetry values from the quasi-free proton were found equal to the ones extracted from a pure proton target. The asymmetries from

Aims: We model the emergence of magnetized plasma across granular convection cells and the low atmosphere, including layers up to the mid-chromosphere. Methods: Three-dimensional numerical experiments are carried out in which the equations of MHD and radiative transfer are solved self-consistently. We use the MURaM code, which assumes local

Photometric time series obtained for CoRoT-2 with the VLT/FORS2 camera in z band during a transit of the planet CoRoT-2b and with the SST/IRAC camera at 4.5 and 8um during an occultation of the same planet. (3 data files).
