Scientific paper

Some attempts to detect Am stars photometrically are presented. They deal with both ground-based photometry (Geneva system) and UV spectrophotometry and photometry from the TD-1 satellite data. For this purpose a reddening-free parameter m is defined in the Geneva photometric system. Spectrophotometric features possibly characteristic of the Am phenomenon are presented. As a conclusion, based on the correlation between spectral classification and the various parameters and features as well as the Kurucz (1979) stellar model atmospheres, the m parameter is found to be most reliable and able to select stars with a high probability of being Am.
