Scientific paper

On the basis of new spectroscopic observations of the double-line spectroscopic binary, 32 Virginis, it is suggested that the primary component is an evolved Am star (or delta Delphini star), of subgiant luminosity. The secondary appears to be a main-sequence star of spectral type near A7. The secondary is thus hotter, but less massive than the primary. As a substantial proportion of delta Delphini stars are known to be delta Scuti variables, the primary is probably responsible for the variability shown by 32 Vir.
