Descripción
Intensity images obtained with the Taiwanish Oscillation Network (TON) are been studied in order to determine the temporal evolution of the horizontal velocity flows detected under the solar surface. A region of the Sun is going to be tracked for several solar rotations. For every new appearance of the region, a ring diagram procedure is going to be applied, and an estimation of the horizontal velocity flows under this solar region will be obtained. The aim of this work is to set the basis of a more complete study, extended to several regions on the solar surface with which the temporal behavior and stability of wider velocity flows may be inferred.

    Design and manufacture of athermalized optomechanical mounts for GRANCAIN, the infrared imaging instrument for GTC's adaptive optics
    GRANCAIN (GRAN CAmara INfrarroja) is a first-light imaging instrument in the infrared J, H and K bands that will be integrated into the adaptive optics focus of the Gran Telescopio de Canarias. The purpose of the instrument is to capture SWIR diffraction-limited images for a field of view of 22x22 arcsec. The instrument boasts a telecentric optical

    Measuring Rotation Periods and Stellar Oscillations in Red Giants with TESS Data
    TESS is a powerful engine for studying stellar variability. However, it has been challenging to adopt methods used for other space missions, such as Kepler, to infer rotation periods and solar-like oscillation frequencies in TESS data. The availability of multiple sectors of data for most targets, improved stability, and the release of new
