Scientific paper

A sample of helium weak stars was surveyed using the low dispersion SWP and LWR cameras of IUE during 1983 to study systematics of the broad continuum feature at 1400 A as a function of effective temperature, spectral anomaly and age. For the Orion association, there are five stars (HD 35456, 36313, 36526, 36668, 37140); for Sco-Cen, there are two (HD 142301 and 144334); and for Alpha Per, there is one (HD 21699). The range from B2 to B6 is covered. Only HD 34452, the most extreme silicon star in the sample, has a very strong 1400 feature.
