Spectrophotometry of peculiar B and A stars. VIII. OMI Aur, 137 Tau, 15 Cnc, 3 Hya, nu Cnc, 17 COM a, 21 Com.
Abstract
Optical region spectrophotometry at 3300-7100 A is presented for seven magnetic peculiar A stars: Omicron Aur, 137 Tau, 15 Cnc, 3 Hya, Nu Cnc, 17 Com A, and 21 Com. The energy distributions of all these stars show moderate to strong 4200 and 5200 broad, continuum features except for Nu Cnc which has a weak 5200 feature and a suggestion of one at 4200. The energy distributions of these Ap stars in the optical region range from those which closely resemble those of normal stars to those which show strong differences. Nu Cnc may be a marginal Ap star.
