Description
The measurement of frequencies, linewidths, and splittings of low degree solar p-modes is a difficult task due, firstly, to time scales involved and, secondly, to the spurious presence of side lobes when data is not collected continuously. However, a long set of observations have been obtained at Observatorio del Teide: a total of 52 months of data, spread over 12 years (1977 to 1989), from which the best ones have been selected. These data allows averaging of power spectra, therefore giving statistical significant profiles for the p-modes, which can be fitted to appropriate functions (i.e. Lorentzian). Such analysis is applied to the data mentioned before and preliminary results of the aforementioned parameters are obtained.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    Phase diversity application on the EST MCAO testbench
    Phase Diversity (PD) is a technique widely used to measure and compensate for Non-Common Path Aberrations (NCPA) in optical systems. Beyond its traditional applications, PD has found further uses in solar astrophysics, where it enhances image quality by processing multiple images to correct residual aberrations. In this work, we introduce a
