NEW ASPECT OF SMALL-AMPLITUDE CEPHEID SU CAS
New 17 high-resolutional spectra of small-amplitude Cepheid SU Cas have been obtained to determine its atmosphere parameters (Teff=6353 K; log g=2.38; Vt=3.25 km s -1 and to measure its radial velocities. The last ones were added to the total RV list (378 values) and using the frequency analysis we...
