Description
In this contribution, we show the capability of STARE to obtain frequencies and amplitudes from high temporal resolution δ Scuti spectra. Lightcurves of 13 new field δ Scuti stars are analyzed and a total of 21 oscillation modes are found in a single field. Noise level in the spectra falls bellow 3 mmag for stars fainter than magnitude 9. Subsequent analysis of the other observed fields, a new location for STARE, as well as the sharing of data with similar projects will provide higher-quality results and a valuable δ Scuti database, which would be useful for follow-up observations.

    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
