Descripción
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.
