In order to improve the understanding of the process of emergence of magnetic flux on the solar surface, we studied the temporal evolution of an ephemeral region using emph{Advanced Stokes Polarimeter} data. We adopted two different approaches: first, we used a Milne-Eddington inversion to obtain mean parameters of the emerging bipole magnetic

We present the results of two XMM-Newton observations of Jupiter carried out in 2003 for 100 and 250 ks (or 3 and 7 planet rotations) respectively. X-ray images from the EPIC CCD cameras show prominent emission from the auroral regions in the 0.2 - 2.0 keV band: the spectra are well modelled by a combination of emission lines, including most

An analysis of high-resolution Stokes observations of two light bridges in the active region NOAA 8990 is presented. The observations were recorded with the La Palma Stokes Polarimeter attached to the Swedish Vacuum Solar Telescope. The stratification of different physical parameters is retrieved using the Stokes Inversion based on Response

We present visible and near-infrared spectra (0.5 2.4 μm) of 11 Near Earth Asteroids obtained with the telescopes at the “Observatorio del Roque de los Muchachos” in La Palma, Spain. A spectral analysis of the obtained data is performed in order to establish the taxonomical classification of the observed asteroids. We use the method outlined by
