Description
The results of a high temporal resolution spectroscopic monitoring of the UV Cet type fare stars AD Leo and V1054 Oph are reported. Intermediate resolution optical spectra of these stars were taken using the IDS spectrograph of the 2.5 m Isaac Newton Telescope (INT) of El Roque de los Muchachos Observatory (Spain) during 4 nights (2-5 April 2001). We have obtained high temporal resolution by taking series of spectra with short exposure times (15-300 sec) separated only by the CCD readout time (~60 sec). The great number of spectra observed each night has allowed us to analyse the temporal evolution of the emission lines and to identify several fares of different intensity and duration.

    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

    Co-phasing the distributed aperture of a Fizeau interferometer via photonic lanterns and machine learning
    The advantage of large optical telescopes from the ground for high-contrast direct imaging relies on achieving exquisite control of the incident optical wavefront. Since the exoplanet problem almost always has a bright star within a small field of view there are usually ample photons for measuring the atmospheric and telescopedistorted wavefront. A
